Description
The color neutral Z boson is an excellent probe of the hot dense matter produced in heavy ion collisions. The products of the Z boson di-lepton decays do not interact with the dense color matter, thus, the Z boson allows us insight into the initial hard scattering that produced it and provides a clean test of our understanding of the collision. The ATLAS experiment has measured Z->ee and Z->mumu in Pb+Pb collisions with sqrt(s_NN)=2.76 TeV in a data sample corresponding to 140 inverse microbarns of integrated luminosity. The measurement of Z boson production and their properties as observed in these interactions will be described.
