$J/ψ$ suppression at FAIR energy collisions and QCD phase diagram    [PDF]

A. K. Chaudhuri

Survival probability for $J/\psi$'s in FAIR energy collisions is studied in a
QGP motivated threshold model. In the threshold model $J/\psi$'s are assumed to
dissociate beyond a threshold temperature $T_{J/\psi}$. Model parameters are
obtained by analysing experimental data in $\snn$=17.4 and 200 GeV collisions.
In low energy collisions, model is sensitive to the QCD phase diagram. The
model predicts that $J/\psi$'s are least suppressed in $\sqrt{s}_{NN}\approx$
40 GeV collisions.
