The symmetry energy E-sym is the part of the nuclear energy associated with the asymmetry in the neutron/proton content. Its relevance is due to the role that it plays in a large variety of systems and processes in nuclear structure, astrophysics and heavy-ion collisions dynamics. In the last ten years many efforts from different fields have been pursued to costraint it density dependence both below and above the saturation density(rho(0) similar to 0.16f m(-3)). Here we briefly sketch the present status on the knoweledge of E-sym at low density, we discuss the on going work at suprasaturation one and we present new perspective that are opening up for the role of E-sym in the transition to quark matter at high baryon density.

Abstract
The symmetry energy E-sym is the part of the nuclear energy associated with the asymmetry in the neutron/proton content. Its relevance is due to the role that it plays in a large variety of systems and processes in nuclear structure, astrophysics and heavy-ion collisions dynamics. In the last ten years many efforts from different fields have been pursued to costraint it density dependence both below and above the saturation density(rho(0) similar to 0.16f m(-3)). Here we briefly sketch the present status on the knoweledge of E-sym at low density, we discuss the on going work at suprasaturation one and we present new perspective that are opening up for the role of E-sym in the transition to quark matter at high baryon density.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
