Rare B meson decays in the Minimal R-symmetric Supersymmetric Standard Model

Taking into account the constraints imposed by experimental data on the parameter space, we analyze the lepton flavor violating decays of B meson in the scenario of the minimal R-symmetric supersymmetric standard model. The prediction of the branching ratios is strongly affected by $\tanβ$ and the off-diagonal entries in the slepton and squark mass matrices. The off-diagonal entries in the slepton mass matrix are constrained by the experimental limits of radiative two body decays of leptons. The off-diagonal entries in the squark mass matrix are constrained by the experimental limits of low energy observables related to B meson physics. The branching ratio of $B^0_d\rightarrow μτ$ is predicted to be four orders of magnitude below the future experimental sensitivity and the decay $B^0_d\rightarrow μτ$ has a higher chance of being observed in the future.

Lepton-flavor violation in the MRSSMSeesaw

The Minimal R-symmetric Supersymmetric Standard Model with Seesaw (MRSSMSeesaw) extends the MRSSM by incorporating right-handed neutrinos to generate neutrino masses via the Type-I seesaw mechanism. This work presents a detailed analysis of lepton flavor violation (LFV) processes, including $\ell_i \rightarrow \ell_j γ$, $\ell_i \rightarrow 3\ell_j$, and Higgs decays $h \rightarrow \ell_i \ell_j$, Based on the current experimental limitations, we carry out detailed parameter scanning and numerical calculations to analyse the effects of different sensitive parameters on LFV.The numerical results show that the non-diagonal elements involving the initial and final leptons are main sensitive parameters and LFV sources.
