Query: Thermodynamical properties of strongly interacting matter in a model
  with explicit chiral symmetry breaking interactions   We analyse the effects of the light and strange current quark masses on the
phase diagram of QCD at finite temperature and vanishing baryonic chemical
potential, computing the speed of sound, the trace anomaly of the energy
momentum tensor and the fluctuations and correlations of the conserved charges
associated to baryonic, electric and strangeness numbers. The framework is a
known extension of the three flavor Nambu Jona Lasinio model, which includes
the full set of explicit chiral symmetry breaking interactions (ESB) up to the
same order in large $N_c$ counting as the 't Hooft flavor mixing terms and
eight quark interactions. It is shown that the ESB terms are relevant for the
description of a soft region in the system's speed of sound and overall slope
behavior of the observables computed. At the same time the role of the 8q
interactions gets highlighted. The model extension with the Polyakov loop is
considered and the results are compared to lattice QCD data.
