Lepton flavour violation (LFV) naturally occurs in many new physics models, specifically in those explaining the $B$ anomalies. While LFV has already been studied for mesonic decays, it is important to consider also baryonic decays mediated by the same quark transition. In this paper, we study LFV in the baryonic $\Lambda_b \to \Lambda \ell_1 \ell_2$ using for the first time a full basis of New Physics operators. We present expected bounds on the branching ratio in a model-independent framework and using two specific new physics models. Finally, we point out the interplay and orthogonality between the baryonic and mesonic LFV searches.

    The LFU ratio R_Λ^{τ/μ} for Λ_b → Λ τ⁺τ⁻ is predicted in the SM with below-10% uncertainty and can be enhanced by several orders of magnitude in EFT models motivated by b→cτν and b→sμμ anomalies.

  2. Correlating lepton flavor violating $b \to s$ and leptonic decay modes in a minimal abelian extension of the Standard Model

    hep-ph 2026-06 unverdicted novelty 3.0

    In the ABCD model, experimental upper bounds on tau to three muons, muon to electron gamma, and related LFV processes constrain branching ratios of LFV B(s) decays in hierarchical order.
