Study the effect of beam energy spread and detector resolution on the search for Higgs boson decays to invisible particles at a future e${}^{+}$e${}^{-}$ circular collider

We study the expected sensitivity to measure the branching ratio of Higgs boson decays to invisible particles at a future circular \epem collider (FCC-ee) in the process $e^+e^-\to…
