Title: The first SÏRIT experiments to constrain the symmetry energy at high density
Abstract: The nuclear equation of state is a fundamental property of nuclear matter that describes relationships between energy, pressure, temperature, density and isospin asymmetry in a nuclear system. The asymmetric part of EoS, which is originated by the isospin asymmetry, has not been well constrained yet above the saturation density, contrary to the symmetric part of EoS. Transport model calculations predict that pions generated by the heavy-ion collisions are sensitive probe to constrain the symmetry energy above the saturation density. The SÏRIT Time Projection Chamber and ancillary trigger detectors were specifically designed and constructed to constraint the symmetry energy at above the saturation density using the radioactive isotope beams produced by the Radioactive Isotope Beam Factory(RIBF) at RIKEN by measuring pions as well as light ions. In this talk, Iâll describe the SÏRIT TPC and the first series of the SÏRIT experiment at RIKEN in Spring 2016 which collected data in 4 collision systems, 132Sn+124Sn, 112Sn+124Sn, 124Sn+112Sn, and 108Sn+112Sn with beam energy of 270 AMeV.
