Exploring dimuon Higgs decay in an extended Scotogenic model

We investigate the dimuon Higgs decay h → μμ in the context of an extended Scotogenic model. The model introduces a singlet complex scalar in addition to the standard Scotogenic scalar doublet and singlet fermions, charged under a dark ℤ symmetry. By exploring the one-loop contributions, we show tha...

Sumario:We investigate the dimuon Higgs decay h → μμ in the context of an extended Scotogenic model. The model introduces a singlet complex scalar in addition to the standard Scotogenic scalar doublet and singlet fermions, charged under a dark ℤ symmetry. By exploring the one-loop contributions, we show that the model allows for sizable deviations in the Higgs dimuon decay rate, quantified by the quotient R = Br(h → μμ)/Br(h → μμ). Crucially, these deviations comply with experimental limits, including those on Br(μ → eγ) and Br(h → γγ). Such deviations can be tested and constrained by future precision measurements at the LHC.
