Georgia State University will be hosting the 3rd collaboration meeting of the sPHENIX collaboration on December 15-17th. Scientists from all over the world are working to build a new detector called sPHENIX at the Relativistic Heavy Ion Collider (RHIC) located at Brookhaven National Lab on Long Island to study the Quark Gluon Plasma, an extremely hot and dense state of matter that formed few microseconds after the Big Bang and is recreated in high-energy heavy-ion collisions. Understanding how this matter behaves improves our knowledge of Quantum Chromodynamics, which describes the strong force, the force responsible for keeping particle bound in the nucleus. The 2015 Long Range Plan of Nuclear Science called sPHENIX “essential” for completing the scientific mission of RHIC. The GSU nuclear physics group led by Dr. Connors, Dr. He and Dr. Sarsour is playing a leading role in the development of the sPHENIX hadronic calorimeter which measures the energy of the particles produced in the heavy-ion collisions and is looking forward to having a productive meeting here at GSU with their collaborators in December.
