Next-to-leading order QCD and electroweak corrections to Higgs-strahlung processes at the LHC

Abstract

In this paper we calculate the total and fiducial cross sections as well as differential distributions for the Higgs-strahlung or VH process pp → VH → lν l /l − l + +H, (V = W or Z, l=e, µ) including QCD and electro-weak corrections up to next-to-leading order before and after reweighting photon PDFs of NNPDF2.3qed, NNPDF3.0qed, MRST2004qed, CT14QEDinc, and LUXqed at the LHC with 13 TeV and Higgs boson mass MH = 125 GeV. The predictions from the various photon PDFs before and after reweighting against each other are in good agreement. The photon PDF uncertainties of the photon-induced cross sections decrease significantly with the reweighting PDFs.

Collider Physics at the Precision Frontier

“…[199], both NLO EW and QCD corrections have been implemented in the program Hawk [181,182]. Combined NLO QCD+EW corrections are also available [200,201], where Ref. [200] con-tains NLO QCD+EW predictions for HV and HV +jet production including parton shower effects.…”

Next-to-leading order corrections for $gg \to ZH$ with top quark mass dependence

“…The NLO electroweak (EW) corrections are given by [10,11]. Combined QCD+EW corrections at NLO are also available [12][13][14]. Despite of these progresses, the theoretical precision is still not enough to match the potential of future LHC and HL-LHC runs [15].…”

$ZH$ production in gluon fusion: two-loop amplitudes with full top quark mass dependence

“…NLO electroweak corrections have been calculated in Refs. [24,25], combined NLO QCD+EW corrections are also available [26][27][28]. Differential QCD corrections to the process pp → ZH have been calculated up to NNLO, including H → b b decays at NLO [29,30] and at NNLO [31].…”
