A New Precision Process at FCC-hh: the diphoton leptonic Wh channel

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, $Wh\to \ell \nu \gamma \gamma$. We estimate the sensitivity to the ${\mathcal{O}}_{\phi q}^{(3)}$, ${\mathcal{O}}_{\phi W}$, and ${\mathcal{O}}_{\phi \tilde{W}}$ SMEFT operators. We find that this channel will be competitive with fully leptonic $WZ$ production in setting bounds on ${\mathcal{O}}_{\phi q}^{(3)}$. 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 ${\mathcal{O}}_{\phi \tilde{W}}$. However, the bounds on ${\mathcal{O}}_{\phi W}$ and ${\mathcal{O}}_{\phi \tilde{W}}$ 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.
