CP violation in loop-induced diboson production

Year: 2025

Type: article

Abstract: A bstract We consider the impact of CP-violating Higgs and top interactions on diboson production from gluon fusion within the Standard Model Effective Field Theory framework. We systematically study differential distributions for double Higgs, double W and Z production and compare their features to those obtained from CP-conserving interactions. For electroweak gauge boson production, we explore the impact of the new interactions on the angular distributions of the leptonic decay products and the associated gauge boson polarisation fractions both inclusively and differentially with the transverse momentum of the gauge boson.
