Probing for new physics with rare charm baryon (Λ c , Ξ c , Ω c ) decays
Abstract We analyze rare charm baryon decays within the standard model and beyond. We identify all null test observables in unpolarized Λ c → pℓ + ℓ − , ℓ = e, μ decays, and study the new physics sensitivities. We find that the longitudinal dilepton polarization fraction F L is sensitive to electrom...
