Parton shower evolution in medium and nuclear modification of photon-tagged jets in Pb+Pb collisions at the LHC
We study the medium modification of jets correlated with large transverse
momentum photons at the LHC via a transport and perturbative QCD hybrid model
which incorporates the contributions from both elastic collisions and radiative
energy loss experienced by the parton showers. Calculations are performed for
the modification of the photon-tagged jet yield, the photon-jet energy
imbalance, and the azimuthal distribution of away-side jets. The modifications
of photon-tagged jets with different values are
studied and they exhibit different centrality and jet cone size dependence due
to traversing different medium lengths and density profiles. We further
investigate the influence of transverse and longitudinal jet transport
coefficients on the nuclear modification of photon-tagged jet production and
jet shape observables.Comment: 11 pages, 15 figure
