$b\to s{\ell }^{+}{\ell }^{-}$ Transitions in Two-Higgs-Doublet Models

Abstract

In this article we study $b\to s{\mu }^{+}{\mu }^{-}$ transitions and possible correlations with the anomalous magnetic moment of the muon ($a_{\mu }$) within two-Higgs-doublet models with generic Yukawa couplings, including the possibility of right-handed neutrinos. We perform the matching on the relevant effective Hamiltonian and calculate the leading one-loop effects for $b\to s\ell {\ell }^{(\prime )}$, $b\to s\gamma$, $\Delta B=\Delta S=2$, $b\to s\nu \bar{\nu }$ and $\ell \to {\ell }^{\prime }\gamma$ transitions in a general $R_{\xi }$ gauge. Concerning the phenomenology, we find that an explanation of the hints for new physics in $b\to s{\mu }^{+}{\mu }^{-}$ data is possible once right-handed neutrinos are included. If lepton flavour violating couplings are allowed, one can account for the discrepancy in $a_{\mu }$ as well. However, only a small portion of parameter space gives a good fit to $b\to s{\mu }^{+}{\mu }^{-}$ data and the current bound on $h\to \tau \mu$ requires the mixing between the neutral Higgses to be very small if one aims at an explanation of $a_{\mu }$.
