Abstract
The increase in luminosity and center of mass energy at the FCC-hh will open up new clean channels where BSM contributions are enhanced at high energy. In this paper we study one such channel, Wh → ℓνγγ. We estimate the sensitivity to the Oφq(3), OφW, and OφW ˜ SMEFT operators. We find that this channel will be competitive with fully leptonic WZ production in setting bounds on Oφq(3). We also find that the double differential distribution in the pTh and the leptonic azimuthal angle can be exploited to enhance the sensitivity to OφW ˜. However, the bounds on OφW and OφW ˜ we obtain in our analysis, though complementary and more direct, are not competitive with those coming from other measurements such as EDMs and inclusive Higgs measurements.
