Next-to-leading order electroweak corrections to $p p \rightarrow \mu^+ \mu^-e^+e^- + X$ at the LHC Collider

Abstract

We present a calculation of next-to-leading-order electroweak corrections to off-shell ZZ production, i.e. pp → µ + µ − e + e − + X. All resonant and non-resonant contributions are included, with finite-width effects treated in the complex-mass scheme. The matrix elements are implemented into Monte Carlo programs allowing for the evaluation of arbitrary differential cross sections. We present integrated cross sections for the LHC at an energy of 13 TeV as well as differential distributions for realistic acceptance cuts applied to the final-state leptons.

NLO QCD effective field theory analysis of W+W− production at the LHC including fermionic operators

“…The SM QCD corrections to W + W − pair production are known to NNLO [16,17], including the effects of a jet veto [18,19]. The EW corrections are typically small [20][21][22], and the combined QCD/EW corrections including leptonic W decays have been implemented [23][24][25]. We perform an analysis including QCD [26] and EW corrections [21], along with modifications of both the three-gauge-boson and fermion couplings.…”
