论文摘要
Proton-Proton Collision中的$ W^+W^-γ$生产为Electroweak对称性破坏机制提供了一个窗口，并直接登录了三重和四重奏量规耦合。仪表玻色子自我互动的精确研究也可能提供了超出标准模型以外的新物理学存在的证据。在本文中，我们研究了LHC上的$ W^+W^-γ$生产以及QCD+EW NLO的未来更高的能量质子proton Collider，包括Parton淋浴效果。我们发现，光子诱导的（即$qγ$ - 和$γγ$引起的）渠道的贡献不可易于获取，因为光子光度可以通过碰撞能量的增加而显着提高，并且大型真实的JET JET发射QCD和EW校正可以通过应用JET VETO VETO SELLECT SELLECT ASSECT FIST SELECT SEPTIOS来降低。此外，我们还研究了由PDF不确定性和分解/重新归一化量表依赖性引起的理论错误。
$W^+W^-γ$ production in proton-proton collision provides a window to the mechanism of electroweak symmetry breaking and a direct accessment to triple and quartic gauge couplings. Precision study of gauge boson self-interactions may also provide evidence of existence of new physics beyond the Standard Model. In this paper, we study the $W^+W^-γ$ production at the LHC and future higher energy proton-proton colliders at the QCD+EW NLO including parton shower effects. We find that the contributions from the photon-induced (i.e., $qγ$- and $γγ$-initiated) channels are non-negligible since the photon luminosity can be enhanced significantly with the increment of colliding energy, and the large real jet emission QCD and EW corrections can be depressed sufficiently by applying the jet veto event selection scheme. Moreover, we also investigate the theoretical errors arising from the PDF uncertainty and the factorization/renormalization scale dependence.
