What have Hadron-Hadron interactions to do with Neutron stars? Maybe nothing.50m
Abstract: Strange hadrons might play a rather crucial role in understanding the composition of the innermost part of neutron stars. Indeed among the many models attempting to describe the core of neutron stars many envisage the presence of strange hadrons. First Hypotheses saw the formation of a condensate composed of antikaons and neutrons as forming the neutron star cores, but the later discovery of extremely massive neutron stars currently disfavor this scenario. More recently Hyperons have been considered more suited candidates within these models but experimental confirmations are still needed. In this talk the tools offered by experiments at accelerators to verify the above-mentioned models will be presented. The state of the art knowledge in the field will be summarized and future perspectives discussed.
