European scientists announced on July 6 that they had discovered a new type of subatomic particle containing a never-before-seen mixture of elementary quarks, forming the most fundamental building blocks of matter.
The above particle, called “Xicc++” , contains two heavy “charm” quarks and one “up” quark, which is four times larger than the baryon particle of the same family as the proton.
According to scientist Matthew Charles, of the LPNHE Laboratory in Paris (France), this matter has been predicted in the Standard Model theory of particle physics and the discovery of this matter “is not a shock. shock”.
Mr. Charles is one of 800 scientists to be named for the discoveries of the particle accelerator (LHC) of the European Organization for Nuclear Research (CERN).
Particle collision activity is most common for detecting the Higgs boson elementary particle, which forms mass on matter.
The Xicc++ bead is a beautiful twin baryon bead that we rarely come across.
The team says this is the first time they’ve seen a Xicc++ particle with two such heavy quarks.
There are six types of quarks, with pretty literal names like “charm” , “strange” or “beauty” . The “charm,” “top” and “bottom” beads are the heaviest.
Quarks form baryons like protons and neutrons, which are the most common in the known universe. Many baryons combine with each other in the atom (atom), forming the molecules that make up matter.
Mr. Charles said Xicc++ is a beautiful twin baryon that we rarely see. Because of its short existence in the early universe, there is no such particle today.
To create them in the lab requires a high concentration of energy, like the kind of energy that can be generated from the newly upgraded LHC machine.
According to the above scientist, Xicc++ is an unstable baryon . It only lives “for a tiny fraction of a second” before disintegrating into other, lighter particles.
The discovery will allow scientists to continue testing the Standard Model of physics – the orthodox theory of the fundamental particles that make up matter and the forces that govern them.
However, it does not help explain dark matter, nor does it explain why there is more matter than antimatter in the universe.
More importantly, this model runs counter to Einstein’s theory of relativity, according to which gravity as we know it doesn’t seem to work at the subatomic level.
Scientist Charles said the biggest task of this work was to try to touch where the Standard Model broke down to find another explanation.
