Scientists at the Large Hadron Collider at CERN have announced the discovery of three alien particles that may help reveal how quarks bind together.Among these "exotic particles", one is a pentaquark (hadron consisting of five quarks) and the other two are tetraquarks. The particles were found by the LHCb collaboration at CERN, which uses a 5,600-ton detector in a section of the Large Hadron Collider to study the differences between matter and antimatter.
- What is the Standard Model of Physics?
Last year, the collaboration found the first doubly absorbing tetraquark, the longest-lived exotic matter particle. found so far. The newly discovered particles add to the growing list of alien particles discovered in the collaboration.
Niels Tuning, physics coordinator of the LHCb experiment at CERN, said: "The more analyzes we do, the We find more types of alien hadrons. We are witnessing a period of discovery similar to that of the 1950s, when the discovery of a zoo of hadronic particles began, and eventually led to the quark model of ordinary hadrons in the 1960s. Now we are creating Particle Zoo 2.0.
Hadrons are strongly interacting subatomic particles made up of quarks and antiquarks. The familiar protons and neutrons that you know are both hadrons and each one consists of three quarks. Quarks come in six flavors (up, down, charm, wonder, head, bottom) that can combine in different ways to make unique particles.

For example of newly discovered pentaquark It is made up of strange, up, down, and charm quarks, as well as a charm antiquark. This is the first known pentaquark with an alien quark. The two new tetraquarks are a pair: one is doubly charged and the other is its neutral partner.
- Understanding the wonders of the
subatomic world in simple language"Finding new types of
tetraquarks and pentaquarks and measuring their properties will
help theorists develop a unified model of alien hadrons,"
LHCb spokesperson Chris Parkes said in a CERN statement. develop,
the exact nature of which is currently largely unknown. This
process will also help to better understand ordinary hadrons.
Ten years ago, the existence of the Higgs boson was confirmed, and Physicists at the Large Hadron Collider continue to find new particles. So far, 66 hadrons have been detected in the collider, and the LHCb collaboration has been responsible for identifying 59 of them. The third run of the Large Hadron Collider began on Tuesday, and Physicists expect the new high-energy collisions to provide better data for uncovering the hidden underpinnings of our universe.
And in addition to new particles emerging from the collisions, data A lot of benefit will be collected. "The search for new particles is not even half of what we do at the LHC," said Freya Blekman, a particle physicist at the University of Hamburg and a contributor to the CMS-FCC-ee collaboration. We also do a lot of studies on how materials stick together and how these known nuclear forces work at a much more detailed level." ) The future of particle physics is as bright as ever.
