Description
This study explores fully leptonic WZ and WW production within the SMEFT framework at NLO in QCD, focusing on both CP-even and CP-odd triple gauge coupling dimension-six operators. We investigate the off-shell production processes and contrast our findings with those derived under the narrow-width approximation. Alongside the conventional kinematical observables, we examine polarisation-related observables and angular coefficients. Moreover, we also assess potential SMEFT effects on asymmetry observables. Furthermore, through a sensitivity analysis, we identify critical LHC observables that are particularly sensitive to SMEFT-induced modifications, thereby shedding light on potential avenues for new physics searches in diboson production at the LHC.
