Next-to-leading order QCD corrections to HZW±HZW± production at 14 TeV LHC

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→HZW±pp→HZW± 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→HZW±pp→HZW± by 45%45%, when mH=125.3 GeVmH=125.3 GeV. We also study the dependence of the LO and NLO corrected cross sections on the renormalization and factorization scale μ  . Besides, due to the unbalance of parton distribution functions, we investigate the charge asymmetry of W±W± in the production of pp→HZW±pp→HZW±, which can reach 32.94%32.94% for μ=(mH+mZ+mW)/2μ=(mH+mZ+mW)/2 at 14 TeV LHC.
