Jet quenching and $\gamma$-jet correlation in high-energy heavy-ion collisions
Abstract
Medium modification of -tagged jets in high-energy heavy-ion collisions is investigated within a linearized Boltzmann transport model which includes both elastic parton scattering and induced gluon emission. In Pb+Pb collisions at TeV, a -tagged jet is seen to lose 15\% of its energy at 0-10\% central collisions. Simulations also point to a sizable azimuthal angle broadening of -tagged jets at the tail of a distribution which should be measurable when experimental errors are significantly reduced. An enhancement at large in jet fragmentation function at the Large Hadron Collider (LHC) can be attributed to the dominance of leading particles in the reconstructed jet. A tagged jet fragmentation function is shown to be more sensitive to jet quenching, therefore a better probe of the jet transport parameter.
