Probing the Symmetry Energy with Strangeness Production

利用奇异产生探测对称能

The EoS of dense matter plays an important role in understanding the later evolution of the universe,the physics associated with compact stars.Therefore,constraints on the equation of state(EoS)of dense nuclear matter has been a longstanding and common goal of both nuclear physics and astrophysics.Nowadays one of the main goals of relativistic heavy-ion collision program is to understand the properties of dense nuclear matter,i.e.,EoS of nuclear matter under conditions of extreme energy and baryon density^([1]).While among all the potential observables used to probe the EoS of dense nuclear matter,strange mesons or baryons are di erent from the rest.
