abstract

The $\mu\nu$SSM, one of supersymmetric extensions beyond the Standard Model, introduces three singlet right-handed neutrino superfields to solve the $\mu$ problem and can generate three tiny Majorana neutrino masses through the seesaw mechanism. In this work, we investigate the rare decay process $\bar{B}\rightarrow X_s\gamma$ in the $\mu\nu$SSM, under a minimal flavor violating assumption for the soft breaking terms. Constrained by the SM-like Higgs with mass around 125 GeV, the numerical results show that the new physics can fit the experimental data for $\bar{B}\rightarrow X_s\gamma$ and further constrain the parameter space.

    hep-ph 2025-02 conditional novelty 5.0 of 10

    The mu-from-nu SSM can reproduce the measured B_s^0 -> mu+ mu- branching ratio while also satisfying the Bbar -> X_s gamma constraint, for certain ranges of At, kappa, upsilon_nu^c, and A_lambda.

  2. $B \to X_{\mathrm{s}} l^{+} l^{-}$ in the $\mu$ from $\nu$ Supersymmetric Standard Model

    hep-ph 2026-07 conditional novelty 4.0 of 10

    In the μνSSM, B→X_s l+l− is dominated by charged-Higgs C7 in the low-q² region and C9/C10 Z-penguins in the high-q² region, with the forward-backward asymmetry set by C7C10 and C9C10 interference.
