Do we know the sign of the gauge-Higgs coupling?

Description

I will explore measurements at the LHC and future colliders that are sensitive to the relative sign of the coupling between the Higgs and the W and the Higgs and the Z. The relative sign of these couplings can be opposite that of the Standard Model in models with Higgs multiplets larger than doublet. Finally, I will explain the caveats in recent experimental searches that claim to measure the sign of the coupling.
