Description
We study CP violation within the Standard Model Effective Field Theory framework, focusing on the impact of CP-odd dimension-6 operators entering gluon-induced double Higgs and double Z and W production. After extending the SMEFTatNLO model to include the relevant operators, we study differential distributions for these processes 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 at the inclusive and differential level. This abstract is based primarily on the work done in arXiv: 2411.00959.
