The paper presents phenomenological results for vector boson pair production at the Large Hadron Collider (LHC) using the parton-level next-to-leading order (NLO) program MCFM. The authors include a new process, $pp \rightarrow \gamma\gamma$, and update existing processes to incorporate fragmentation contributions for experimental isolation of photons in $\gamma\gamma$, $W\gamma$, and $Z\gamma$ production. They also account for gluon–gluon initial state contributions for all relevant processes. The results are presented at the current operating energy of $\sqrt{s} = 7$ TeV and for the ultimate machine goal, $\sqrt{s} = 14$ TeV. The impact of these predictions on several important distributions relevant to searches for new physics at the LHC is investigated. The paper covers various diboson processes, including $\gamma\gamma$, $W\gamma$, $Z\gamma$, $WW$, $WZ$, and $ZZ$ production, and discusses the role of isolation cuts, final-state radiation, and scale variations. The results are compared with experimental data from CMS and ATLAS collaborations, showing good agreement with the Standard Model expectations.The paper presents phenomenological results for vector boson pair production at the Large Hadron Collider (LHC) using the parton-level next-to-leading order (NLO) program MCFM.
