22 Dec 2011 | | Abstract: | Two major aspects of strange particle physics at the upcoming FAIR and NICA
facilities and the RHIC low energy scan will be discussed. A new distinct
production mechanism for hypernuclei will be presented, namely the production
abundances for hypernuclei from $Lambda$’s absorbed in the spectator matter in
peripheral heavy ion collisions. As strangeness is not uniformly distributed in
the fireball of a heavy ion collision, the properties of the equation of state
therefore depend on the local strangeness fraction. The same, inside neutron
stars strangeness is not conserved and lattice studies on the properties of
finite density QCD usually rely on an expansion of thermodynamic quantities at
zero strange chemical potential, hence at non-zero strange-densities. We will
therefore discuss recent investigations on the EoS of strange-QCD and present
results from an effective EoS of QCD that includes the correct asymptotic
degrees of freedom and a deconfinement and chiral phase transition. | | Source: | arXiv, 1112.5284 | | Services: | Forum | Review | PDF | Favorites | |
