phosphorusPhysicists at CERN’s Large Hadron Collider announced todayHe discovers three exotic particles that may help reveal How quarks are bound together.

One particle is a pentaquark (hadron composed of five quarks), the other two are Four quarks.they were found LHCb Collaboration At CERN, it uses a 5,600-ton detector on part of the Large Hadron Collider to study the difference between matter and antimatter.

Last year, the Collaboration discovers first double charm tetraquark, the longest-lived exotic matter particle ever discovered. Newly discovered particles increase cooperation”s A running list of foreign particles.

“The more analyses we do, the more species of strange hadrons we find,” LHCb physics coordinator Niels Tuning said in a statement. Released by CERN“We are witnessing a period of discovery similar to the 1950s, when the ‘particle zoo’ of hadrons began to be discovered and culminated in the quark model of traditional hadrons in the 1960s. We are creating ‘Particle Zoo 2.0’.”

Hadrons are strongly interacting subatomic particles composed of quarks and antiquarks. The protons and neutrons you’re familiar with are both hadrons; they’re each made up 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.”

Ten Yesterday many years ago, Existence of Higgs boson confirmed, physicists at the Large Hadron Collider continue to search for new particles.sixty-six To date, hadrons have been discovered at the collider, 59 of which were caused by LHCb.This Third run of the Large Hadron Collider begins todayphysicists expect that very energetic collisions will provide better data to unravel hidden The foundation of our universe.

In addition to the new particles created by collisions, there is a lot of useful data to collect. “Finding new particles isn’t even half of everything we do at the LHC,” Freya Blekman, a particle physicist at the University of Hamburg and a contributor to the CMS and FCC-ee collaboration, told last week’s video call. Gizmodo. “We’ve also done a lot of research on how matter sticks together and how these well-known nuclear forces work on a more detailed level.”

With the advent of the High Brightness Large Hadron Collider, the future of particle physics is as bright as ever.
