The Large Hadron Collider beauty (LHCb) collaboration has said that three new strange particles have been found. Up until recently, these kinds of strange particles had only been thought about. Quarks are the building blocks of these strange particles.
“Like the protons and neutrons that make up the nucleus of an atom, these new particles are made up of quarks,” said Chris Parkes, Professor of Experimental Particle Physics at The University of Manchester. “Protons and neutrons, on the other hand, are made up of three quarks, while strange particles are made up of four or five quarks.”
Theorists thought that exotic particles were possible about 60 years ago, but they have only been seen in the last 20 years by LHCb and other experiments.
Professor Parkes says, “Finding strange particles and measuring their properties will help theorists build a model of how these particles are made, even though the exact nature of these particles is mostly unknown.” “It will also help us understand the theory behind everyday particles, like the proton and neutron, better.”
The results, which were shown today at a CERN seminar, add three more strange particles to the list of new ones that have been found at the Large Hadron Collider (LHC). They will help physicists figure out how quarks come together to make these bigger particles.
The LHCb collaboration is a group of over a thousand scientists from twenty different countries. It made one of the four big detectors at CERN’s Large Hadron Collider (LHC) and runs it. Professor Parkes is in charge of the collaboration, and more than twenty staff and PhD students from The University of Manchester work on the project.
The new research shows that the international LHCb collaboration has seen three particles that have never been seen before: a new type of “pentaquark” and the first pair of “tetraquarks.”
