Abstract

Since the precise study of Higgs gauge couplings is important to test the Standard Model (SM), we calculate the complete next-to-leading order QCD(NLO QCD) correction to the $pp \to H Z W^{\pm}$ production in the SM at 14 TeV LHC. Our results show that the NLO QCD correction can enhance the leading-order cross section of $pp \to H Z W^{\pm}$ by 45%, when $m_{H}$ = 125.3 GeV. We also study the dependence of the LO and NLO corrected cross sections on the renormalization and factorization scale $I^¼$ . Besides, due to the unbalance of parton distribution functions, we investigate the charge asymmetry of $W^{\pm}$ in the production of $pp \to H Z W^{\pm}$ , which can reach 32.94% for $I^¼ = (m_{H} + m_{Z} + m_{W}) /2$ at 14 TeV LHC.
