Measurement of the transverse momentum distribution of Z/γ * bosons in proton-proton collisions at s=7 TeV with the ATLAS detector

A measurement of the Z/γ * transverse momentum (pTZ) distribution in proton-proton collisions at s=7 TeV is presented using Z/γ * →e + e - and Z/γ * →μ + μ - decays collected with the ATLAS detector in data sets with integrated luminosities of 35 pb -1 and 40 pb -1 , respectively. The normalized dif...
