In relativistic heavy ion collisions at RHIC and the LHC, a quark–gluon plasma (QGP) is created for short duration of about 10 fm/c. Quarkonia (bound states $$c\bar{c}$$ $$b\bar{b}$$ ) are sensitive probes this phase on length scales comparable to size bound which less than 1 fm. Observations quarkonia in these provide us with lot information how presence QGP affects various quarkonium states. ...

Penetrating probes in heavy-ion collisions, like jets and photons, are sensitive to the transport coefficients of produced quark-gluon plasma, such as shear bulk viscosity. Quantifying this sensitivity requires a detailed understanding photon emission jet-medium interaction nonequilibrium plasma during hydrodynamic stages collisions. Up now, an has been hindered by instabilities. These instabil...
