Effects of hadronic rescattering in mini-jet production and energy loss at the LHC

Abstract

We present an extension of hybrid approach, which combines viscous hydrodynamics, particlization, jet energy loss and hadronic cascade, to describe data in the intermediate and high $p_T$ regimes. This enables us to study mini-jet production and energy loss in heavy ion collisions, in conjunction with the bulk dynamics of QGP fireball. This hybrid approach is applied for Pb-Pb collisions at the LHC with $\sqrt{s_{NN}} = 2.76\,\textrm{TeV}$, and we demonstrate that hadronic re-scatterings have significant effects on mini-jets with intermediate $p_T$.
