According to foreign media reports, the Large Hadron Collider (LHC) recently detected a new subatomic particle during the atom crush experiment. This is a beautiful particle. Newly discovered particles have long been predicted by theory, but have never been discovered.
The new particle is called Xi(b)* and is a baryon. It is reported that the baryon is composed of three smaller substances called quarks. The protons and neutrons that make up the nucleus are also baryons. Xi(b)* Particles belong to the so-called beauty barter, which contains a bottom quark, also known as a beautiful quark. Although the discovery of Xi(b)* is not necessarily a surprise, this discovery should help scientists solve the bigger problem of how matter is formed. James Alexander, a physicist at Cornell University who conducted experiments on the Large Hadron Collider, said: "This is another brick on the wall."
Unlike protons and neutrons, Meizi’s lifespan is extremely short. Xi(b)* decays into the other 21 short-lived particles in less than a second. The beauty bark needs extremely high energy to create it, so it is not found elsewhere on the planet except at the center of atomic accelerators, such as the Large Hadron Collider at the European Centre for Nuclear Research (CERN) in Geneva.
Scientists at the Large Hadron Collider did not directly discover this new particle. Instead, they saw evidence of its decay. The Compact Muon Solenoid (CMS) detector of the Large Hadron Collider captured new particles. The process of decay in a messy aftermath after the collision of protons and protons. Vincenzo Chiochia, a physicist at CMS, said: "Looking for this particle is really hard. Finding this complex decay in such a chaotic situation gives us confidence in our ability. In the future, we can also find other new particles."
Scientists at CMS stated that the existence of this new particle has been confirmed. The researchers have 99.99% confidence that this result was not accidental. Patrick Lukens, a scientist at Fermilab who was not involved in the study, said: "This discovery further confirms that the physicists' understanding of how quarks fit together is essentially correct."
This particle has been predicted by a very successful theoretical model in physics, called quantum chromodynamics, which demonstrates how quarks combine and how to create heavier particles. However, Lukens said that finding Xi(b)* had no effect on finding the Higgs boson. The Higgs boson can explain why mass exists in the universe. It is also a particle predicted by a quantum chromodynamic model. (Shang Li)
