Measurement of W production in pp collisions at √s =2.76 TeV with the ATLAS detector — •Ksenia Gasnikova for the ATLAS collaboration — DESY, Notkestrasse 85, 22607 Hamburg, Deutschland

Probing W production cross-section in pp collisions for a range of center of mass energies from 2.76 to 13 TeV provides additional constraints for the parton densities functions. This talk presents the measurement of W cross-section at √s = 2.76 TeV in 2013 data in electron and muon decay channels. Based on integrated luminosity 4 pb⁻¹ collected in 2013 there are around 13k selected events and this leads to precision of the cross-section measurement at a few percent level.
