The discovery of the particle, whose position, unlike the Higgs boson, has been accurately predicted will allow us to learn more details about the strong nuclear force, the same force that holds, for example, the atomic nuclei that include the protons and neutrons
The Large Hadron Collider (LHC) at CERN has discovered the first new particle since it started operating in 2009.
The particle, (Chi_b (3P) will help scientists better understand the forces that hold matter in the universe. The article appears in a preprint version on the Arxiv server. If the discovery is indeed proven, it will be possible to learn from the particle how the universe is built. The mass of the particle is 7 tera electron volts. Unlike the Higgs boson, whose location is still being tested later The announcement last week about finding clues to its existence, the current particle is predicted by the standard model, and its rarity is what prevented its discovery until today.
The particle, Chi_b (3P) is a Chi particle with a more excited state than seen in previous accelerator collisions. The particle consists of a "beauty quark" and a "beauty antiquark" connected together. The existence of the particle has been predicted for several years but it has not actually been discovered until now.
Prof. Yoram Rosen from the Faculty of Physics at the Technion and a member of CERN says in a conversation with the science website: "Particles of a certain type, for example those containing the b quark, form a whole series starting with the lightest - Zoni B, and ending with the heaviest Chi and Sigma - every such particle you know Down to the lighter and therefore more common particles. That's why sometimes the chance of producing the particle can be surprising is almost negligible because it is a particle that may break up even before it is formed. The importance comes from the fact that the presence of such a particle shows to some extent the forces that hold it. The particle is interesting because it tells us new things about the force that holds the quark and the antiquark together - the strong nuclear force, the same force that holds, for example, the atomic nuclei that include the protons and neutrons."
According to him, the reason it was discovered only now, and not in the two and a half years that have passed since the start of the LHC's operation, and not even in the Permilab accelerator, is that now the LHC has reached an energy level sufficient to produce it in the collision of protons, and also the large amount of data generated in every particle collision at the LHC overshadows the data produced in Primilab.

In short, you pull the appeal 🙂
yes Yuval,
I am the unsteady and stirring particle, it was written when I had just woken up and was tender in unsteady vigilance.
Maybe you meant "excited"? excited
to Mirum
more exited state I think translates to 'a more unsettled state'.
There are indeed quite a few problems in the article:
1. It is not yet clear how exactly the particle differs from the food received at SLAC.
2. I assume that "exciting state" refers to the Charmness feature that exists in foods, although this is just a wild guess and until someone edits this article in a serious way, we won't know.
For the avoidance of doubt only:
There is no pending response from Yehuda in the system.
On the other hand, a comment that was censored even before it was written is a comment that the person who intended to write it censored himself.
Are you dying to know what comment Yehuda wanted to write but was censored?
Mirom Golan
Not that I understand it, but I guess the difference is in the mass of the protons at the time of the collision (inside the accelerator).
To the editor
Possessive particle - "exciting state"?????
R.H. Rafai.M
So what is the difference? What causes the mass differences if both particles are made of the same elementary particles?
Sabradamish Yudhala,
Pleasant friction.
Here, I gently responded.
😛 🙂
Yehuda,
You slander and then ask them to respond gently? Doesn't that seem a bit problematic to you? 🙂
Mirom Golan
If I'm not mistaken, the particle you talked about is a different (lighter) particle.
The discovered particle is a heavier particle, with more mass.
If so, isn't this the composite particle we're talking about? http://en.wikipedia.org/wiki/Bottom_eta_meson
According to the Wikipedia article it was first seen 3 years ago
Yuval Chaikin why are you surprised, for example there are comments that are censored even before they are written.
It is similar to this particle!
Please respond gently
Shabbat Shalom

Read here: http://en.wikipedia.org/wiki/Quark
In the past, bottom and top quarks were sometimes referred to as "beauty" and "truth" respectively, but these names have somewhat fallen out of use.
What energy intensity has the accelerator reached to date? And how much is it in percentages in relation to its planned maximum capacity?
Thank you Ehud.
If so, should there be "a particle that may disintegrate even before it is detected", and not as written?
mirom,
True, there are only 6 types of quarks and the b quark is called by two names, sometimes read
He has a bottom and is sometimes called beauty.
to Aria,
Indeed, magic sometimes has something to do with beauty, but not in this case.
jubilee,
A particle is a bound state of quarks. The binding energy between the quarks determines the half-life
his, i.e. how long will it take for him to fade to a more stable state. Sometimes the bond energy is very small
so that it does not allow the particle to be identified before it breaks down.

Mirom - refers to a magical quark (charm).
Avi,
What the hell.. is this a "beauty quark"? There are only six types of quarks and none of them are called that.
Thank you, my father, for filling the hole I have in my literary education 🙂
All the descriptions here are taken directly from "The Hitchhiker's Guide to the Galaxy"
Leave you...in the end it will be 42.
?A particle that may disintegrate even before it is formed?
