Abstract

The correlation of jets with neutral bosons is a particularly powerful tool to probe the underlying physics of jet quenching. To gain insight into the physics of this process we can study Z boson + jet and photon + jet correlations. Because the Z boson and photons do not directly couple to the strong force, in a jet + boson event the unmodified bosons allow us to access the modification of the opposite side jet; unlike dijet events, where both jets potentially lose energy, these bosons provide an excellent calibration of the energy of the recoil jet. The ATLAS experiment has measured jet correlations with direct photons as well as with Z bosons via dilepton channels in Pb + Pb collisions with √sNN=2.76 TeV in a data sample of nearly 0.15^{nb -1} of integrated luminosity. Both boson + jet analyses show modification of the jet momentum relative to the boson momentum qualitatively consistent with jet quenching.
