LHCb discovers a new type of tetraquark at CERN
The LHCb collaboration has observed an exotic particle made up of four charm quarks for the first time
Teams of researchers from EPFL and University of Zurich are members of the LHCb collaboraiton and have made major contributions to the construction and operation of the detector
The LHCb collaboration has observed a type of four-quark particle never seen before. The discovery, presented at a recent seminar at CERN and described in a paper posted today on the preprint server, is likely to be the first of a previously undiscovered class of particles.
The finding will help physicists better understand the complex ways in which quarks bind themselves together into composite particles such as the ubiquitous protons and neutrons that are found inside atomic nuclei.
