From all-round academic master to chief scientist - Chapter 202 Black hole discovered? !

When the time came to the last second, an embarrassing scene occurred.

Because when everyone was staring at the screen, they found to their amazement that it was stuck at 1 second remaining.

Of course, this is common for computer progress bars.

After about 5 seconds passed, finally, the progress bar changed from 99% to 100%.

Then, the data displayed on the screen took everyone’s breath away once again.

I saw that the energy spectrum and wave spectrum images had changed, the lines on the images had changed, and a lot of data had also changed.

This change is due to the disappearance of those noises.

The data without noise immediately made the physicists present feel a sense of “refreshing”.

For physicists, seeing the meaning behind an image is a basic ability. For example, by looking at one of the wave peaks, they can know that this thing is a sign of the decay of the Z boson. Another example is that the proton is It doesn’t turn into a neutron.

In particular, the vast majority of physicists present are world-class physicists, and their physical abilities are needless to say.

Looking at such images, they all wanted to express their comfort!

As for the data that has not been processed by the root search method before, they are far from being able to judge it at just one glance. It takes at least four or five glances.

After such a brief silence, the room finally erupted into cheers.

“pretty!”

“Perfect!”

“Awesome, damn!”

“Lin Shen 666!”

…

As an international research organization, there are people from various countries here, so scientists from all countries can’t help but express their praise in their own language.

This processing result is enough for them to call it perfect. I don’t know how much help it will bring to them when they process data in the future, including time saving, convenience during analysis, and accuracy of the final result. sex.

All in all, this has demonstrated the success of the root investigation method.

And this was not over yet. After a while, another pop-up window appeared next to it, which was an evaluation of the efficiency of this processing.

I saw this pop-up window showing: [This processing efficiency is 91%-97%! 】

The appearance of this pop-up window pushed the atmosphere of the audience to a climax.

The lowest estimated processing efficiency is as high as 91%, which is enough to show how powerful this method is.

In ten years, there have been billions of collisions, and the processing efficiency can still be as high as 91%, which is enough to illustrate the large amount of data it processes.

At this moment, everyone in the audience looked at the young man at the front and showed their gratitude to him.

Research in high-energy physics will open a new chapter starting from today, and all of them working in this industry will be the beneficiaries.

If nothing else, for publishing papers, this simple root search method can provide their academic community with thousands of papers, such as randomly finding a previous high-energy physics paper. , and then use the root search method to ‘renovate’ the data of these papers, process it again, and then there will be a brand new paper, which can be published to journals, or even to journals that are better than the paper before the renovation. .

Therefore, each of them would like to thank Lin Xiao for his root investigation method.

Even Peter Higgs’s eyes were slightly red, and his pupils were even a little moist.

However, the moisture in his eyes did not stop the excited light in his eyes.

For him, there are no regrets in life. The Higgs particle, which he has been pursuing all his life, was confirmed eight years ago at this place.

Even if you ask him what else he pursues in life, he may feel that there is nothing to pursue.

However, people obviously always have a pursuit, to be able to see any breakthrough achievements in the physics world, or something that can benefit the physics world, and obviously, Lin Xiao has done it for him twice.

In particular, this root investigation method also plays an extremely important role in the future development of physics.

So, he walked up to Lin Xiao very solemnly, grabbed one of Lin Xiao’s hands with both hands, shook it tightly, and said, “Mr. Lin, thank you.”

Seeing the old gentleman like this, Lin Xiao was a little stunned, and then said with a smile: “Mr. Higgs, this is my interest. I pursue it not to gain gratitude from others.”

Higgs shook his head and said: “The great ones think that is what they should do, but gratitude is what the beneficiaries should do.”

“If multidimensional field theory is your talent to prove that you are as outstanding as Einstein in physics, then the ‘mathematical vaccine’ is a sufficient condition to prove your greatness, because it is a blessing to each of us. .”

“So I have to thank you, at least, for showing me that our physics can still thrive even after I’m gone.”

Listening to Higgs’ words, Lin Xiao nodded slightly, then smiled and said: “Okay, you are right.”

Higgs smiled, patted Lin Xiao’s shoulder again, and said, “Haha, in the end, I hope you can make more achievements for which we are grateful.”

Lin Xiao smiled: “As long as my brain hasn’t stopped thinking, I will always pursue it.”

“good!”

Higgs praised him, and then said loudly to the people around him: “Friends, how can we not applaud such a young scholar?”

Then, he clapped again and slowly backed away, moving himself away from the center of people’s vision.

People once again applauded Lin Xiao.

Looking at this scene, Lin Xiao shrugged helplessly, and then clapped as well.

As the applause gradually subsided, the celebration for root investigation came to an end.

Then, Lin Xiao said: “Okay, let’s leave the matter of root investigation until later to celebrate. Don’t forget the real purpose of our project, which is to measure the mass of the W boson!”

“Now, since our experimental data has become so concise and clear, let’s start now to find those traces that may represent W bosons!”

“I believe that based on the current data results, we will have every chance of finding traces of the W boson!”

After hearing Lin Xiao’s words, those who belonged to the project team all shouted: “Okay!”

“Then, let’s get to work!”

Afterwards, many people present returned to their seats and began to screen the data and images inside, and then based on the various properties of the W boson, they determined which traces may belong to the W boson. dice.

Although the W boson decays quickly, it is no longer impossible to find it in today’s “clean” data.

In addition, they will certainly not give up the previous method of measuring W boson, which is to study it through its decay products. In the past, because there were many interferences in the experimental data, even if they wanted to use the decay products to study It is also very complicated, but the current experimental data is relatively more convenient, so they can continue to use this old method to measure again, and the measurement accuracy will definitely be more accurate than before.

In this way, as time slowly passed, someone finally cheered: “I seem to have found a particle that is very consistent with the W boson!”

Hearing his voice, people immediately paid attention.

After hearing the news, Lin Xiao couldn’t help but pay attention and said, “Send it to the big screen.”

Then, the big screen jumped and several images appeared.

In the energy spectrum, it is a suddenly rising peak. In the past data, this peak will basically be regarded as an experimental error and will not be paid much attention to. But now if we combine it with the analysis of its trajectory and momentum, Analysis shows that this is indeed consistent with the various data of the W boson.

For example, the mass of the W boson is 80GeV/c. If this peak value is used to calculate the energy formula, the mass obtained is very close to the value of 80GeV/c.

In addition, its trajectory is also very short, just like a point. Unless you magnify it many times, you can find that it is actually an arc. If it were placed in the past, this point would definitely be affected by the noise around it and would also be affected by physics. Scientists regarded it as a noise, but its appearance at this time made everyone have the idea of ​​​​exploring it.

“It does seem to be very similar to the W boson?”

“You can do the calculations.”

People discussed it.

Lin Xiao discussed it with several professors next to him, and finally determined that if nothing else happened, it was the W boson.

Then Lin Xiao applauded and encouraged: “Well done, this is indeed a W boson. Okay, let’s continue, try to find as many as possible, and then we will use the root search method to find them all.” Mark it!”

The root search method can not only be used to find noise, but can also be used to mark all traces that may be W bosons. Of course, the premise is that they first find the W boson and then determine the mark of the W boson. and its common characteristics.

So now they need to find some more samples.

“good!”

After hearing Lin Xiao’s words, the researchers present all responded. At the same time, because of this first success, they became more motivated.

Now, the distance between them and success has become visibly shorter.

Seeing that the researchers were once again engaged in work, Lin Xiao smiled slightly, then lowered his head and continued to look at his things.

He did not search for W bosons with these researchers. As the general person in charge, after he gave out the methods, the work of applying the methods was naturally handed over to his subordinates.

But now, he is doing something more important.

That is, looking for some new discoveries that may emerge from the current ‘clear’ experimental data.

In the past, the complex experimental data made it easy for them to ignore some strange but regular data, but now, they have a better chance of discovering these data.

Of course, it is not that easy. If we used to look for needles in the Yellow River, now we are looking for needles in a relatively clean lake. There are still difficulties.

However, after looking through many data images, Lin Xiao really found nothing special. Over this period of time, many people discovered data that might be the W boson.

After watching for a long time, he suddenly felt a little thirsty. Lin Xiao called Sterling to get him a glass of water. Then he came behind Professor Witten and looked at the data he was studying.

However, Witten’s expression seemed serious at this time, as if he had discovered something.

Lin Xiao couldn’t help but ask: “Witten, have you discovered anything?”

“This energy zone makes me very puzzled. You see, its energy is actually as high as 2 TeV or more! This is really incredible.”

Lin Xiao looked down and nodded slightly, “Indeed, this energy is a bit too high.”

Generally, the energy will eventually be around the unit of GeV, reaching TeV, which is the level of trillions of electron volts, which is really amazing.

Of course, it is not ruled out that these are noisy data that have not been successfully processed.

Because the ATLAS detector where their data comes from observed collisions of particle beams with energies up to 7 TeV, it is indeed possible to record such high energies if affected by noise.

Both of them looked at this data and fell into thinking.

This is the case with scientific discoveries. An inadvertent discovery may bring them extremely important enlightenment.

Perhaps this discovery is indeed noise, but what if it is a surprising discovery?

After a while, Lin Xiao suddenly had a surprising idea.

Then he immediately said: “Share this data to the big screen.”

Witten was stunned, then did as Lin Xiao said, and asked at the same time: “Do you have any ideas?”

Lin Xiao replied: “Hawking radiation.”

When he heard these two words, Witten’s eyes suddenly showed an incredible expression.

Hawking radiation? !

He thought carefully in his mind and suddenly felt that Lin Xiao’s speculation was not impossible.

Hawking radiation is a phenomenon related to black holes speculated by Hawking based on the theory of quantum effects. It refers to the heat emitted by black holes due to the evaporation effect.

In the LHC, because the collision energy has reached the TeV energy level, according to theoretical predictions, it is entirely possible to knock out a black hole.

In other words, Lin Xiao judged that this sudden increase in energy peak was due to Hawking radiation. As long as the identification is true, it means that they have really created a black hole!

And this will be a huge impact on the physics world.

In the past, no one could detect Hawking radiation. After all, it required observation of black holes. But now, their means of observing black holes are still greatly limited. It was extremely difficult to take photos, let alone take them. To determine whether it radiates energy.

Therefore, this has led to the fact that Hawking radiation has always been doubtful, and there has always been controversy in the physics community.

And if their observations are true, it will have an impact on the debate about black holes in the physics community.

At this time, the relevant data had been shared on the big screen, and then Lin Xiao shouted to everyone: “Everyone, pay attention! Look at this energy peak that suddenly rises on the big screen, and look for something similar to it. Other data.”

“If it were possible, we might… discover black holes.”
