| $J/\Psi$ suppression: Medium modified heavy quark potential and equation of state |
| |
|
| Content: |
We have proposed an equation of state of strongly coupled quark-gluon
plasma in the framework of strongly coupled electromagnetic plasma with
appropriate modifications to take account of color and flavor degrees
of freedom and QCD running coupling constant. To do so we have derived
the expression for plasma paramter, $\Gamma$ (defined as the ratio of average
potential energy to average kinetic energy) incorporating the
nonpertubative effects, present at and/or beyond $T_c$ to explain
the nonideal behavior of QGP. Our results on thermodynamic observables
{\em viz.} pressure, energy density, speed of sound etc. nicely fit the
results of lattice equation of state with gluon, massless and as
well {\em massive} flavored plasma. Motivated by this excellent agreement with
lattice equation of state we apply our model to estimate the
$J/\psi$ suppression in an expanding dissipative strongly interacting
QGP produced in relativistic heavy-ion collisions and
reproduce the experimental results on $J/\Psi$ suppression. |
