The newly-discovered particles, named Σb(6097)+ and Σb(6097)-, are predicted by the quark model, and belong to the same family of particles as the protons that the Large Hadron Collider (LHC) accelerates and collides: baryons, which are made up of three quarks. But the type of quarks they contain are different: whereas protons contain two up quarks and one down quark, the new particles are bottom baryons composed of one bottom quark and two up quarks or one bottom quark and two down quarks respectively.The LHCb researchers found these particles using the classic particle-hunting technique of looking for an excess of...
