For example, photons are the most familiar type of gauge boson to us.

The particle that gives mass to fundamental particles is the Higgs particle—this is quite complex to elaborate on. Although the mass of fundamental particles comes from the Higgs particle, the primary source of visible mass in the universe is actually the strong interaction, which is a concept at the doctoral level. In summary, it's enough to just have a conceptual understanding of it.

On the other hand,

these fundamental particles can form a vast number of composite particles, and the number of composite particles depends on what scale you are discussing.

If it is at the atomic level, just the various elements and their isotopes alone number in the thousands.

If you specifically refer to subatomic particles, then you're usually considering mesons and baryons, along with some special particles.

For instance, photons have 225 types of structures, electromagnetic elements have 2,700 types of structures, and so on.

This is akin to how we've classified birds into a species, but birds can also be further divided into sparrows, doves, eagles, and a bunch of other categories.

Humans are similar; they can be classified as non-European Emperor, or divided into male, female, and Hideyoshi.

Thinking about this.

Xu Yun pondered for a moment, then clicked a few times on the browser's bookmark page.

He opened a website named Ming Sect's pdgLive.

This is a website that professionally collects subatomic particle information, where you can find a large amount of information about subatomic particles.

This includes those confirmed by experiments and with measured properties, those proven to exist by experiments, those theoretically existing, as well as new theoretical predictions.

Then Xu Yun switched back to Aurora software, changing y(xn+1) to y(xn+2), and ran it again.

Soon,

the software simulated a binding energy number:

1.26342MeV.

"1.26342MeV..."

Xu Yun noted down this number and began comparing the mass peaks against the invariant mass spectrum on the website.

Currently, although scanning tunneling microscopes can 'see' atoms, it's actually a metaphorical phrase.

In scientific research, the true verification of new particles still relies on colliders and some other equipment.

The specific method, to be honest, is simple: it's all about one word:

Boom.

You smash particles with a collider, then measure and analyze the data like scattering cross-sections to create charts and graphs.

For example, a collision process produces a muon; muons will decay into other particles, and thus the mass peak of muons can be found on the invariant mass spectrum.

The costs for a single detection event are genuinely astronomical, so Aurora's simulation numbers obviously cannot compare in precision.

Thus, 1.26342MeV is not an exact value and requires another round of screening.

"1.379867MeV.... too high....."

"1.129973MeV.... this is too low....."

"1.14514MeV, still not enough...."

Xu Yun continued to compare them row by row in this way.

His eyes began to feel strained, but he didn't dare slack off at all.

A few minutes later,

his eyes suddenly focused, locking tightly onto one of the entries:

"Huh? 1.26812MeV?"

This was the closest binding energy level he had found so far to the Aurora's displayed figure, with only a two-decimal-point difference.

Seeing this,

he immediately moved the mouse and clicked on the information.

A moment later,

Xu Yun's pupils constricted heavily, almost exclaiming out loud in the library.

At this very moment,

a line of information was clearly written on the screen in front of him:

Particle name:

Lambda Hyperon (4685)

Discovery date:

November 18, 2022.

Discovery unit:

Huaxia University of Science and Technology, Zhao Zhengguo.

.......

Note:

Today happens to be a holiday, called World Best Buddies Day.....

Is there really no connection between the two?

The true answer might be unknown to anyone, but Xu Yun personally believes it is negative.

Using Xiaoli's name to name this new type, whether in terms of meaning or sentiment, is a very suitable choice.

However, Qiu Sheng was unable to understand the thoughts in Xu Yun's mind; he simply felt that the name seemed okay and said:

"Old Xu, this name isn't bad, and since it's a new type you discovered, you can call it whatever you like, I have no objections."

Xu Yun nodded to him, pondered for a moment, and then asked:

"By the way, Old Qiu, what do you think about that donkey's hair growth solution?"

Qiu Sheng frowned in thought for a while, then slowly shook his head and said:

"I heard in novels that Bat Lady's blood can make Gou Mei grow hair, but in reality, we can't find an inhuman lady who has been poor for ten thousand years, so this is obviously impossible."

"The remaining methods are nothing more than black sesame or minoxidil—my suggestion is to use both simultaneously. After all, the donkey seems quite tolerant to that kind of stuff, and it probably won't be an issue."

Minoxidil might not be very commonly known, but it is actually one of the mainstream internationally recognized drugs for treating hair loss, with a very high usage rate.

However, its effectiveness is somewhat limited, barely better than a placebo; it's like picking the tallest among the short.

Black sesame is probably more familiar to everyone, known alongside Polygonum multiflorum as one of the two traditional dietary supplements for hair growth.

Calling it nonsense or an IQ tax is definitely not the case, but its efficacy is also relatively limited.

However, considering there are no particularly effective methods at present, these two things have become the only choices.

Of course.

Hair growth is only a short-term measure; what's more important is to breed—it's not good to keep relying on Brother Lv too much.

However, these days it's rather difficult to find a purebred domestic LP phenotype female donkey because there are simply too many hybrid donkeys in the country.

Classmates who were donkeys in their past lives should know.

A donkey's lifespan is generally 20 years, which is about over a hundred years in human terms.

That means donkeys from 2000 years ago, whether male or female, have more or less died out.
