Abstract

We present new results of next-to-leading order (NLO) electroweak corrections to doubly-polarized cross sections of W+WW^+W^- production at the LHC. The calculation is performed for the leptonic final state of e+μeμνˉμe^+\mu_e \mu^- \bar{\nu}_\mu using the double-pole approximation in the diboson center-of-mass frame. NLO QCD corrections and subleading contributions from the gggg, bbˉb\bar{b}, γγ\gamma\gamma induced processes are taken into account in the numerical results. We found that NLO EW corrections are small for angular distributions but can reach tens of percent for transverse momentum distributions at high energies, e.g. reaching 40%-40\% at pT,e300p_{T,e}\approx 300 GeV. In these high pTp_T regions, EW corrections are largest for the doubly-transverse mode.
