This event is part of the Preliminary Oral Exam.
Examining Committee: John Butler, Tulika Bose, Shyamsunder Erramilli, and Ken Lane
The measurement of weak vector boson production cross section at hadron colliders provides an early look into possible new physics signatures as well as a test of our understanding of QCD and EW processes at a new energy scale. The relatively large cross section and easily identifiable decays to leptonic final states offer a clean experimental signature which can be measured to high precision even with a relatively small amount of data. In addition theoretical predictions are well known and available at NNLO accuracy in QCD and NLO accuracy in radiative EW processes. In this talk I'll present the measurements of the W->lν and Z->ll production cross sections in proton-proton collisions at sqrt(s) = 13 TeV using data recorded by the ATLAS experiment at Large Hadron Collider, corresponding to a total integrated luminosity of 81pb^(-1).
