Description
Diboson production at the LHC is already setting competitive bounds on anomalous triple gauge couplings (aTGC) for certain types of theories due to the increase in energy. Within the SMEFT, the leading contributions at high energy to this process depend on a combination of aTGC plus other operators. Until now the contribution of these other operators was negligible due to being very constrained by LEP. Recent works have pointed out that a reevaluation of this assumption may be necessary due to the increase in accuracy of the aTGC. In this work we study the impact of these previously neglected operators on the aTGC bounds and find that they may be non-negligible in certain cases. We also make some projections and estimate their impact on future aTGC studies. While doing this, we also notice that a global fit of LEP + Diboson (@LHC) may improve the current constrains on certain vertex corrections (when set only using LEP).
