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 \( {\mathcal{O}}_{\varphi q}^{(3)} \), \( {\mathcal{O}}_{\varphi \mathrm{W}} \), and \( {\mathcal{O}}_{\varphi \tilde{\mathrm{W}}} \) SMEFT operators. We find that this channel will be competitive with fully leptonic WZ production in setting bounds on \( {\mathcal{O}}_{\varphi q}^{(3)} \). We also find that the double differential distribution in the \( {p}_T^h \) and the leptonic azimuthal angle can be exploited to enhance the sensitivity to \( {\mathcal{O}}_{\varphi \tilde{\mathrm{W}}} \). However, the bounds on \( {\mathcal{O}}_{\varphi \mathrm{W}} \) and \( {\mathcal{O}}_{\varphi \tilde{\mathrm{W}}} \) 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.
