Description
Diboson production processes constitute an interesting probe of New Physics related to the Higgs boson and the EW sector. We study the 𝑊ℎ and 𝑍ℎ production processes, with leptonically decaying gauge bosons and both $h\to b\bar b$ and $h\to\gamma\gamma$ decay channels. We study these processes in the SMEFT framework and derive bounds on six dimension-6 operators. The possibility of using the $h\to\gamma\gamma$ decay channel is exclusive to FCC-hh and is an example of new processes made available on this collider. On the other hand, the $h\to b \bar b$ channel is already available at LHC and offers a direct comparison between hadron colliders. We compare the reach and features of each channel at FCC-hh. Finally, we analyse and stress the complementarity of these measurements with EW precision measurements to be carried out at FCC-ee. Based on arXiv: 2004.06122, 2011.13941, and 2208.11134.
