Abstract

We construct an equation of state (EOS) including the hadron-quark phase transition by the Gibbs conditions for finite temperature. We adopt the equation of state based on the relativistic mean field theory for the hadronic phase taking into account pions and the MIT bag model of the deconfined 3-flavor strange quark matter for the quark phase. The gravitational collapse of a massive star is computed using our equation of state and we find that the interval time from the bounce to the black hole formation, namely the duration time of the neutrino emission, becomes shorter for the model with pions and quarks. This fact implies that we may be able to probe observationally the EOS of hot dense matter in future.
