Chapter 218 The new copy is about to be opened

Although it is still unclear what happened to that special particle, it actually had an extremely brief interaction with the Λ hyperon.

But in a sense.

It is precisely because of the ultra-high energy erupted in a short period of time by this interactive phenomenon that Academician Pan and others were able to locate the impact trace so easily.

At this moment.

Academician Pan is on the operating table, analyzing the reports obtained with Zhao Zhengguo:

"The measurement result of the decay parameters is 0.633±0.002, which is higher than the original Λ hyperon accuracy."

"But the observation level is 140Mev. This is the property of electrically neutral mesons."

"Electrically neutral mesons?"

Zhao Zhengguo was stunned for a moment, then blurted out:

"How is this possible?"

"Not to mention that there is already a π meson inside it that has interacted with it. Judging from the integral data of the differential width of the entire process, its spin is a semi-odd number, so it cannot be a meson."


Academician Pan also nodded solemnly.

Considering that many students have limited understanding of particles and cannot distinguish the concepts of baryons and leptons.

Therefore, here we will popularize the concept of particles in a more standardized way. (This is probably a piece of popular science that no one has done before. If you are confused, I suggest you take a look)

First let’s be clear.

That is macroscopic matter, which is ultimately composed of microscopic particles.

Microscopic particles, from large to small, are molecules, atoms, protons and neutrons (nuclei), and finally elementary particles.

And elementary particles.

It is the smallest microscopic substance that is currently indivisible.

Indivisible here means that without volume and model images, its internal structure cannot be detected.

That is, it can be treated as a point particle, which is a concept similar to a particle.

As for elementary particles, they are mainly composed of four categories:

Quarks, leptons, gauge bosons and the Higgs particle.

These four major types of particles are further divided into 61 types of particles.

Among them, the first two quarks and leptons are also called fermions - they constitute the first observable structure of matter.

There are six categories of quarks, called six-flavor quarks, namely up, down, top, bottom, strange, and charming. (Yesterday, you looked like a Jie and stretched your head towards me)

At the same time.

Each flavor quark has three internal degrees of freedom, called colors, so 3X6=18.

And these 18 types of quarks have their own antiparticles, so there are 36 types of quarks in total.

This number corresponds to the 61 above, which is 36 of the 61 types of particles.

There are 12 types of leptons, including the neutrinos mentioned before and so on.

Therefore, there are 12+36=48 types of fermions.

As for gauge bosons and Higgs particles, they are collectively called bosons, which are particles with an integer spin.

Among them, gauge bosons convey the fundamental interactions between particles.

The Higgs field in which the Higgs particle resides is responsible for generating static mass.

Therefore, the Higgs particle was isolated and became its own type, nicknamed the God particle.

And in gauge bosons.

There is only one type of boson that plays a role in electromagnetic interaction, and that is the photon.

As for weakly interacting bosons, there are three.

They are W+, W- and Z bosons respectively.

The transfer particles of the strong interaction are called gluons, and there are eight types in total.

Therefore, the total number of bosons is 1+1+3+8=13.

13+48=61, which constitutes the 61 most basic particles in the world.

Other than that.

There is also a graviton that has not been experimentally proven. These 61 (62) particles constitute the standard model of particle physics.

Of course.

In the most cutting-edge theories, many people believe that the Standard Model is just a low-energy approximation of a larger model. It is good for everyone to understand this, and there is no need to delve too deeply into it.

After having 61 kinds of basic particles, the microscopic world began to put together building blocks, and a new concept emerged:

composite particles.

For example, protons and neutrons are composite particles composed of three quarks and gluons, and are a type of baryon.

As for Chaozi, the word is exactly what it means.

It refers to baryons that are heavier than protons and neutrons and contain at least one strange quark.

Atom = proton (quark + gluon) + neutron (quark + gluon) + extranuclear electron.

Atoms are also called "elements". There are 118 known elements. Elements constitute molecular compounds, and what follows are chemical concepts. (Is this worth a monthly pass?)

As for the meson mentioned by Academician Pan, it is also a type of composite particle.

It has an integer spin and is a boson.

The spin of baryons is semi-odd and they are fermions.

The difference between the two particles is impossible to make a mistake unless you are an interstellar player.

Just like a piece of meat is placed in front of you, you may not necessarily be able to tell whether it is beef, pork or donkey meat.

But no matter what, you can't judge it as a potato.

Then Academician Pan opened the document to a page and said slowly:

"It's really strange that particles with different properties have extremely similar observational magnitudes"

"Just like a fat man and a thin man running a thousand meters, the fat man must consume more energy for the same distance."

Talk about this.

Academician Pan's hand movements suddenly stopped, and with a slight sigh, he paused.

See this situation.

Zhao Zhengguo on the side couldn't help but ask:

"Xiao Pan, have you thought of anything?"

Academician Pan nodded when he heard this, picked up a pen and paper from the table, and drew a simple diagram:

"You see, if a fat man and a thin man are asked to run a thousand meters with their legs, the energy consumed by both sides must be different."

"But if the fat man flew over or even teleported over, is it possible that each other's energy level consumption is in the same range?"

"The orbit calculated by Xiao Xu is the runway. We know that particles will move through this orbit, and we also know that it may trigger quantum tunneling-this is why I will be there."

"But we don't know how it will reach the 'end', we just subconsciously think it is 'running', are you right?"

After hearing what Academician Pan said.

Zhao Zhengguo was slightly stunned at first, then pressed his hands heavily on the operating table, leaned over, stared at the report on the table, and said in horror:

"Xiao Pan, are you saying that the trajectory of this particle is not a jump, but a flicker?"

Academician Pan pulled back his sparse hair, took a deep breath, and affirmed:

"That's right."

Mentioned a long time ago.

Academician Pan is currently a leader in the field of quantum encryption in China. On May 6, his team just used the "Mozi" quantum science experimental satellite to complete the remote transmission of quantum states between two ground stations 1,200 kilometers apart. (Do you still remember the content of the chapter on the shelf? You can talk about it now, hehe.)

The core technology of long-distance quantum state transmission is quantum teleportation, which is the prototype of the teleportation array.

That is to say, using the atmosphere as a channel, a photon from 1,200 kilometers away can be instantly transmitted to you.

However, what technology can currently do is transmit more than ten photons, and there is still a gap of hundreds of billions of orders of magnitude between transmitting photons to the human body. It is a technology that is as difficult as the finale of Conan.

Therefore, the main application of quantum encryption is encrypted communication, that is, network security applications. This is a more practical and realistic direction.

But now.

A variable seems to have appeared.

If the operating mode of this special particle is really flickering, then this means that it has the properties of a quantum state innately!

To know.

Mentioned above.

Photons are the only bosons with electromagnetic interaction, so all current experiments can only use photons as entangled light sources.

But now if there is a hyperon-like particle with this property, it means that reversible quantum logic operations between different degrees of freedom may be performed from another angle!

This is like when you are researching weapons, all you can use is black gunpowder, and you can only use the most primitive methods to develop and correct weapons.

But suddenly one day you wake up and find a bag of Octogen next to your bed.

This is really worthy of a terrifying sentence

Said without politeness.

This particle alone may not win the Nobel Prize. After all, only Higgs, the proposer of the Higgs particle, has ever won this honor for a new type of particle. The characteristics of the new particle are still a long way from the "God particle". long distance.

But on the other hand.

If we can rely on this particle to achieve a breakthrough in certain technical barriers, then this achievement has a high probability of winning a Nobel Prize!

Then Zhao Zhengguo thought for a while and asked:

"Xiao Pan, this particle was discovered by you and Xiao Xu, master and apprentice. How about you give it a name."

"Name"

When Academician Pan heard this, he suddenly felt a complex emotion in his heart.

It was an inexplicable feeling of loneliness, like a ghost wandering alone.

Then he was silent for a moment and said:

"Just call it a lone point particle."

at the same time.

Yongcheng, hundreds of kilometers away.

Not long ago, after reaching an intention to cooperate with Zhou Shan, Xu Yun followed Lin Zhenhua to bid farewell and returned to Hanhua Group.

Since the entire transition metal production line is still being poured at this time, there are still some links that may require assistance from Xu Yun and others, so Xu Yun and the others still need to stay in Yongcheng for two or three days.

So after returning to the park.

Xu Yun, who traveled to many places in the past few days, was a little exhausted, so he hurriedly said goodbye to Lin Zhenhua, told Tang Li a few words not to disturb him, and then returned to his room in the guest house.

Then he felt relieved and took a shower in the bathroom, getting ready to go to bed to see if Tifa had any new videos.

Then unfortunately.

I don’t know if the subtitle team is fishing these days. Xu Yun basically didn’t find anything new, so he could only regretfully give up on his ideas.

But just when I was sitting with my hand on my vagina and sighing.

Xu Yun's heart suddenly moved slightly, and he sensed something.

Then he quickly got out of bed, pressed the door lock, and closed the curtains tightly.

Then he returned to bed and recited the ‘spell’:

"."

After a while.

The surroundings suddenly became dark.

When the light came on again, Xu Yun had already appeared in that mysterious space.

I only see this moment.

The second door that originally disappeared into a space-time photo album has still not been filled in, and the first door where Maverick's letter once appeared has no abnormalities.

But

Originally, the knowledge point was still the third door of 73/100, but the number displayed at this time was impressively.

100/100.

In other words.

The third copy has reached the time when it can be opened. (End of chapter)
