Abstract:

The electroweak boson production is an important benchmark measurement in ultrarelativistic heavy-ion collisions which can provide constraints on the nuclear modification of parton distribution functions. In this paper the results from the proton-lead collision data taken in early 2013 are presented. The Z boson production cross section is measured in bins of the Z boson rapidity and transverse momentum and compared to theoretical predictions. The Z boson production is observed to be proportional to the number of elementary nucleon-nucleon collisions. The forward-backward ratio of the measured cross section is presented.
