Explaining anomalies of B-physics, muon $$g-2$$ g - 2 and W mass in R-parity violating MSSM with seesaw mechanism
Abstract The recent experimental results including $$R_{K^{(*)}}$$ R K ( ∗ ) , $$R_{D^{(*)}}$$ R D ( ∗ ) , $$(g-2)_\mu $$ ( g - 2 ) μ and W mass show deviations from the standard model (SM) predictions, implying the clues of new physics (NP). In this work, we investigate the explanations of these an...

| description | Abstract The recent experimental results including $$R_{K^{(*)}}$$ R K ( ∗ ) , $$R_{D^{(*)}}$$ R D ( ∗ ) , $$(g-2)_\mu $$ ( g - 2 ) μ and W mass show deviations from the standard model (SM) predictions, implying the clues of new physics (NP). In this work, we investigate the explanations of these anomalies in the R-parity violating minimal supersymmetric standard model (RPV-MSSM) extended with the inverse seesaw mechanism. The non-unitarity extent $$\eta _{ee}$$ η ee and the loop corrections from the interaction $$\lambda '\hat{L} \hat{Q} \hat{D}$$ λ ′ L ^ Q ^ D ^ are utilized to raise the prediction of W mass through muon decays. We also find that the interaction $$\lambda '\hat{L} \hat{Q} \hat{D}$$ λ ′ L ^ Q ^ D ^ involved with right-handed (RH)/singlet (s)neutrinos can explain the $$R_{K^{(*)}}$$ R K ( ∗ ) and $$R_{D^{(*)}}$$ R D ( ∗ ) anomalies simultaneously when considering nonzero $$\lambda '_{1jk}$$ λ 1 j k ′ . For nonzero $$\lambda '_{2jk}$$ λ 2 j k ′ , this model fulfills the whole $$b\rightarrow s\ell ^+\ell ^-$$ b → s ℓ + ℓ - fit but cannot be accordant with $$R_{D^{(*)}}$$ R D ( ∗ ) measurements. The explanations in both cases are also favored by $$(g-2)_\mu $$ ( g - 2 ) μ data, neutrino oscillation data and the relevant constraints we scrutinized. Furthermore, this model framework can be tested in future experiments covering, e.g., the predicted lepton flavor violations (LFV) at Belle II and the Future Circular Collider with $$e^+e^-$$ e + e - beams (FCC-ee), as well as the heavy neutrinos at future colliders. |
