| contents | We investigate the dimuon Higgs decay $h \to μ^+μ^-$ 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 $\mathbb{Z}_2$ 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 $R_{μμ} = \text{Br}(h \to μ^+μ^-)/\text{Br}(h \to μ^+μ^-)_{\text{SM}}$. Crucially, these deviations comply with experimental limits, including those on $\text{Br}(μ^{+} \to e^{+}γ)$ and $\text{Br}(h \to γγ)$. Such deviations can be tested and constrained by future precision measurements at the LHC. |
