Description
We present the results achieved for a project dealing with
lattice QCD thermodynamics in the presence of two dynamical
quark generations employing the twisted mass discretization
for Wilson-type quarks and an improved gauge action in order
to ensure (automatic) O(a) improvement of lattice artifacts.
We fix the (charged) pseudo-scalar meson mass values at 400 MeV
and around 250 MeV. The temperatures range from 150 to 650 MeV.
A fixed-lattice scale approach is used at three different
lattice spacings in order to control the approach to the
continuum limit. The effect due to the inclusion of the
second quark generation is studied by comparing with previously
obtained two-flavour results at the higher pseudo-scalar mass
value.
