Title: Characterization of quark gluon plasma as seen through the energy loss of heavy quarks Author:Sheikh, Ashik; Ahammed, Zubayer Contributor:Ahammed, Zubayer (pacrepositoryorg) Subject:Quarks ; Density Ratio ; Bulk Density ; Entropy ; Quantum Chromodynamics ; Energy Dissipation ; Shear Viscosity ; Quark-Gluon Plasma ; Ionic Collisions Description:
The shear viscosity to entropy density ratio ({\eta}/s) of quark gluon plasma produced in ultra- relativistic heavy-ion collisions has been studied from the energy loss of heavy quarks in QGP medium. We have also studied the bulk viscosity to entropy density ratio ({\zeta}/s) and fluidity measure(F) of the medium using the obtained {\eta}/s values. In addition to that, we have estimated the heavy quark bound state potential (V) inside this medium. Our finding of {\eta}/s agrees well with the results obtained by Lattice QCD (LQCD) and functional renormalization group technique.

Title: Event-by-event fluctuations of mean transverse momentum in AuAu collisions in STAR experiment at relativistic heavy-ion collider Author:Ahammed, Zubayer Subject:Mean transverse momentum ; fluctuations Description:
We report results on event-by-event fluctuations in mean transverse momentum in AuAu collisions at $$\sqrt {^s NN} = 130$$ GeV measured by the STAR experiment at RHIC. The dynamical fluctuations, $$\sigma _{\langle P_t \rangle ,dynam} $$ is found to be about 1.2 ±02% of the mean transverse momentum for particles in pseudo-rapidity range of −0.5 < η < 0.5 and for the top 6% central collisions.
