PPhysicists at CERN’s Large Hadron Collider announced todayHe discovered three external particles that could help reveal How quarks are bound together.

One particle is Pentaquark (a Hadron consisting of five quarks) and the other two are Tetraquark was found by them LHCb collaboration At CERN, which uses a 5,600-ton detector on a part of the Large Hadron Collider to detect differences between matter and antimatter.

Last year, d Collaboration found the first double-charm tetraquark, The longest-lived foreign matter particles found so far. Newly discovered particles add collaboration ‘Running list of external particles.

“The more we analyze, the more types of external hadrons we find,” said Nils Tuning, LHCB physics coordinator. CERN has been published. “We are witnessing a similar discovery in the 1950s, when a‘ particle zoo ’of Hadron began to be discovered and eventually led to the quark model of Hadron that was prevalent in the 1960s. We are creating ‘Particle Zoo 2.0’.

Hadrons interact strongly with subatomic particles composed of quark and anticoark. Your known protons and neutrons are both hadrons; Each consists of three quarks.

Quarks come in six flavors (up, down, charm, strange, top and bottom), which can combine in different ways to make up unique particles.

For example, the recently discovered pentaquark is made of strange, up, down and charm quarks, as well as a charm antiquark. It’s the first known pentaquark to contain a strange quark. The two new tetraquarks are a pair: one is doubly charged, and the other is its neutral partner.

“Finding new kinds of tetraquarks and pentaquarks and measuring their properties will help theorists develop a unified model of exotic hadrons, the exact nature of which is largely unknown,” LHCb spokesperson Chris Parkes said in the CERN release. “It will also help to better understand conventional hadrons.”

Years ago yesterday, The existence of the Higgs boson was confirmed, And physicists at LHC continue to search for new particles. Sixty-six Hadrons have been discovered in the collider so far and LHCb is responsible for 59 of them. The The third race of LHC has started todayAnd physicists hope that very strong collisions will provide better data for unpacking hidden objects. The foundation of our universe.

And in addition to the new particles that come out of the collision there is plenty of useful data to collect. “The search for new particles is not even half of what we do at LHC,” Freya Blackman, a particle physicist at the University of Hamburg and contributor to CMS and FCC-EE, told Gizmodo in a video call last week. . “We also do a lot of studies on how matter stays together and how these well-known nuclear forces work at a more detailed level.”

With the high-brightness Large Hadron Collider on the horizon, the future of particle physics is as bright as ever.
