Tech Hammer

Ning Wei was mentally prepared for the ridicule of the entire physics community.

In fact, he also knew that there was no need to talk so much on the day of the banquet, and he was not very keen on doing anything to force his wits down. But there is no way. From a safety perspective, he has to stand up and attract a wave of firepower.

Human attention is limited, and it is better to let CERN's management worry about the aftermath than to check the data after everyone withdraws. Ningwei is very assured of March's abilities, but he never underestimates people's abilities.

Facts have already proven that no matter how sophisticated the technology is, once it is done, it will always leave some clues, just to see if it will be discovered.

At this time, the unreasonable speech diverts everyone's attention, and the chance of some things being discovered is much smaller. The more jokes and jokes there are, the easier it is to take them lightly.

As long as people can look away, they will find that when a person's status reaches a certain level, things like face or reputation don't actually need to be that concerned.

Those who slander often cannot decide how you live your life; and those who can determine your future do not need to use such despicable means of slander. It just so happens that Ningwei has always seen clearly in this regard.

A bunch of foreigners can make fun of them as much as they like...

Seriously speaking, it's impossible for him to lose a hair because of those jokes.

It would be better if those foreign graduate students studying artificial intelligence are ashamed to quote his papers when writing their papers. Under the current circumstances, it will probably be difficult to graduate.

After all, it is still difficult to find a new way. Continuing the past method of adjusting parameters is now mostly not recognized. The emergence of March has changed the entire expectation for artificial intelligence technology.

This is also the reason why Ningban students are extremely popular even though the overall employment situation is not very good.

Almost all companies researching artificial intelligence are willing to pay big prices, whether domestic or foreign.

Yes, although Ning Wei is very unpopular, his students are still very popular, and this is actually enough.

Of course, Ning Wei actually doesn't have time to pay attention to those random jokes or sarcasm.

I traveled for a whole month and had a lot of fun, but the whole September has passed and there are a lot of things that need to be dealt with when I come back.

Not to mention the subsequent data processing work.

Although it talks about setting up a dedicated team to analyze and process the data obtained from CERN, this is just an excuse. After communicating with Luo Zhiqiang, the professor knew little about Ning Wei's ideas, let alone others.

So the data analysis still has to be done by myself with the help of March.

In fact, Ning Wei is indeed rooted in the base of the China Artificial Intelligence R\u0026D Center these days, facing countless data selected in March every day. About half of the day is spent processing fresh new data, and the other half is spent analyzing and studying data from previous inventories.

The difference between the two is still very big.

With the advancement of technology, detectors are upgraded, sensitivity and algorithms are improved, and the data fed back are becoming more and more accurate. After a month of busy work like this, one person and one cat finally achieved some results.

"In March, all statistical data for the energy region above 13TeV after May 2026 will be compiled."

Ning Wei gave the instruction.

It’s not that we don’t need previous data, it’s mainly because CERN’s LHC started to upgrade in 2013. Before that, the record for the highest collision energy level of the LHC was only 8TeV. It wasn’t until the upgrade was completed in May 2016 that the world’s largest Only then did the sub-collider have the ability to collide with 14TeV. Next is the suspension of operation in 2018, with Linac4 replacing Linac2, which has been running for 40 years, and then until 2026, a new generation of LHC will come online, and will be maintained again a year later, until it starts operating again this year...

There was a lot of raw data available, but the LHC was still lagging behind at that time. The LHC that will be re-operated after 2026 has been renamed the High-Brightness LHC. In addition to accelerating particles to higher energy levels, it has also improved infinitesimal precision. The improvement in precision also means that more things that have not been discovered before can be discovered. Phenomenon.

At this time, Ning Wei had obviously discovered something interesting from the data compiled in March.

Ning Wei carefully read the dense data stream and began to discuss with March in the system: "Is there a difference in the data before and after, making the central value of Mw deviate from the standard model by 10-100MeV?"

"Meow...the previous one is the data before the correction of the ATLAS detector, and the next one is the data after the correction."

"Oh, this should be used to correct PD based on the property that the normal differential cross section produced by bosons in the Drell-Yan process is proportional to PDF."

"Meow……"

"In March, there are too many free parameters, and it is still difficult to suppress error divergence under high energy."

"Meow... Do we need to make corrections through energy calibration and selection efficiency, and conduct digital simulations using existing data?"

"Well, let's do it first!"

The kitten raised its paw, and then a huge collider appeared in the room, and then the collider started...

In fact, these are unnecessary. After all, the virtual interpretation does not mean that CERN's LHC was moved to the capital of China in March. It was just to simulate a three-dimensional animation so that Ning Wei could have an immersive feeling. The benefits It can make people feel immersed in the scene, but the disadvantage is that it will waste some computing power.

Fortunately, March is unprecedentedly powerful at this time, and a little computing power is no longer a big deal. In fact, this process is quite unfriendly. Watching the white light representing the electron beam spin in circles is probably like starting a large program on an old computer. Watching the mouse turn into a circle and keep spinning means the same thing. Keeping people waiting, but now with added visual effects...

However, it can also be seen from here that reprocessing existing data is also a huge project for March. It has been a long time since we have seen this circle. However, Ning Wei can also understand that additional calibration may bring more errors. March can try its best to avoid errors through algorithms, but this requires trading time for efficiency.

I'd rather arrive than be in a hurry, and simply take advantage of this moment to make myself a cup of tea.

Although he still doesn't like these coffee and tea drinks, he has been working for five hours and still needs some caffeine to refresh himself.

The way to make tea is as crude as ever. I throw some tea leaves into the big porcelain jar and pour the hot water from the water dispenser directly into it. I then hold the cup and continue to watch the three-dimensional animation simulated in March. When the tea leaves unfold and cool down a little, I see March. There was still no result here, so Ning Wei simply continued to analyze the data.

This is probably the most time-consuming simulation, but there are too many uncertainties in particle collisions of this intensity. Coupled with the possible fallacies of the probe, if you want to perfectly restore the effective data at the moment of collision, This is a very difficult matter. This is true even for March, I can only wait with peace of mind.

Finally, after Ningwei finished two cups of tea and went to the toilet in the middle, the kitten reacted.

"Meow... To complete the data reconstruction, this simulation process accurately recorded the track direction and energy. The momentum calibration included the calibration of energy size and resolution, and through identification, separation and trigger condition selection, the hadron background and From the trajectories of b/c quarks, million mesons, and K meson muons.”

"Meow... Through data comparison, it can be determined that there is one or more layers of spatial orientation misalignment when the internal detector of the LHC records momentum, causing the captured data to be different from the one or more layers when the internal detector records muon momentum. The spatial orientation is misaligned, and the reconstruction simulation process solves the alignment problem to the greatest extent."

"Meow... This simulation introduces a global correction term and uses low accumulation data for global correction. However, it does not ensure that the instantaneous real data can be perfectly restored. It can ensure that the main representations of hadron recoil in the real and simulated data are distributed in the error The degree of agreement within the range is better than the original data. The final data can be obtained as follows..."

Soon the data began to flood the screen again, but this time the data given in March was divided into two rows. The left side was the original data obtained from CERN, and the right side was the new data after re-simulation and calibration using the original data...

The data is finally out.

Ning Wei also began to carefully read the new data after the digital simulation in March, and soon made a discovery.

"Focus on the separation state of the spray column of leptons and hadrons."

"Meow……"

"In March, help me calculate the shape and proportion of the QCD background through simulation data!"

"Meow...the separation parameters need to be recalibrated, please wait..."

Fortunately, the amount of calculation was obviously not that large this time, so Ning Wei didn't have to wait for long, and soon the data was listed in front of the screen...

"Meow...data has been generated and it can be determined that the QCD background shape and proportion vary linearly around specific separation parameters."

"March, linear change? Can it be directly inferred to a higher signal range and simulate its topology through existing data?"

"Meow...the data is being processed, please wait...the reverse inference is completed and the data reduction structure simulation is carried out..."

Ten minutes later, images of microscopic instantaneous particle collisions began to repeat in the room. Probably due to limitations in computing power, although the entire process had been extremely slow, the resolution was still not satisfactory.

This feeling is very annoying. Ning Wei found that he was already on the edge of discovery. At this time, it was as if he already had the key to the door, and he already knew the approximate direction of the door. Now he was just one short Let him find the specific coordinates and insert the key into the door...

So fiercely, Ning Wei thought of something and said hurriedly: "In March, can the resolution be improved by moving the entire energy area around the leptons?"

"Meow... The overall removal will include the energy in the overlap area with the hadron injection, which can improve the resolution, but will affect the completeness. If you want to forcibly improve the resolution, you can also use the experimental data and statistical errors in each channel. Do it in half.”

"Well, let's do it like this."

"Meow...please wait for the data restoration structure simulation and reconstruction..."

This time Ningwei waited for another full half hour...

When the re-brewed tea had reached the bottom, classmate March finally gave the result again. Ning Wei immediately devoted himself to the research of the latest data. After a moment, a look of surprise appeared on his face, and then he became more and more excited...

"March, have you noticed? Have you noticed? It's gone... It's really gone... The amount of transverse momentum and mass are unbalanced! It's completely unbalanced! It's not because the half-life is as simple as half-life, it means that they themselves are unbalanced. My algorithm is probably right!”

"Meow... It is recommended to fit this data with the conventional calibration method."

"Stop suggesting it, do it quickly! Complete the real simulation sample correction simultaneously and use the latest data obtained this time!"

"Meow... Directly retrieving the latest data will have unpredictable consequences. The data traffic is huge, which may cause CERN to find abnormal data flow. It is recommended to simulate step by step!"

"Don't worry so much at this time! What are you afraid of?! What will happen if they find out? Do these people dare to rush to China to trouble me?! Just use it!"

"Meow... it may trigger protests and re-test the network..."

"March is not the time to be afraid. At most, you will temporarily lose the right to use a big house. But if the verification is successful, do you know what will happen? They will cry and beg and kneel in front of you and take the initiative to The ownership of that house is given to you!"

"Meow... Master, you are too excited and your heart rate is too high for long-term scientific research activities. This new model fitting will take a long time. Please wait patiently..."

"March, why didn't I realize you talked so much nonsense before! Hurry up!"

…

China Artificial Intelligence Frontier Technology Research Center, accommodation area.

Liu Wei was sitting at his desk in his room writing a report.

Very melancholy...

In fact, for this trip to Europe, he had already completed the report early, but was sent back and asked to rewrite it...

The reason...

The main reason is that Liu Wei hopes to beautify Ning Wei's trip as much as possible, but obviously there are too many people paying attention to Ning Wei's trip. God knows how many people secretly paid attention to Ning Wei's special plane when it landed smoothly at the Beijing International Airport in the golden autumn of October. He breathed a sigh of relief.

So his words that glorified Ningwei and worked hard in Europe were severely criticized.

You still have to seek truth from facts...

But this report is really difficult to write. Is it possible to just say that Academician Ning went out for a whole month in the name of scientific research? This thing is kept in the archives and will be declassified later. How can we still establish the image of a majestic scientist?

However, the things that Luo Zhiqiang and Jack Ness did were even more inconvenient to write in a report. They were reported in the form of oral reports. Although they may also be formed into paper documents, the higher confidentiality level does not belong to his reports. within the scope.

So damn...

Just when Liu Wei really didn't know how to write, the sound of messy footsteps suddenly reached his ears. As soon as he raised his head, the door was pushed open violently, and then Ning Wei rushed in directly, with messy hair and red face. He rushed in with eyes wide open...

"Fuck, FUCK, Baga, Xiba...Brother Liu, I succeeded! I actually succeeded? Fuck, this world is actually like this? How dare you believe it is really Like this?! Fuck, fuck, fuck! It’s like this?”
