Abstract
The long lifetime of the
quark-gluon plasma likely to be created
in relativistic heavy ion collisions at RHIC and LHC energies
renders it sensitive to the details of the equation of state
of the quark matter. We show that the
pT dependence
of
the survival probability of the directly produced
at
RHIC energies and that
of the directly produced
at LHC energies is quite
sensitive to the
speed of sound in the quark matter, which relates the pressure
and the energy density of the plasma. The transverse expansion
of the
plasma is shown to strongly affect the
suppression at
LHC energies.
