Multiboson production at multi-TeV lepton colliders as complementary probes to rare Higgs decays

Dario Buttazzo, Keshav Chaudhary, Roberto Franceschini +1

We study the potential of very high-energy lepton colliders to probe effective operators affecting the loop-induced Higgs boson decays $h\to \gamma \gamma$ and $h\to Z\gamma$, providing constraint…
