Probing for New Physics with Rare Charm Baryon (${\Lambda }_c$, ${\Xi }_c$, ${\Omega }_c$) Decays

Marcel Golz, Gudrun Hiller, Tom Magorsch

We analyze rare charm baryon decays within the standard model and beyond. We identify all null test observables in unpolarized ${\Lambda }_c\to p{\ell }^{+}{\ell }^{-}$, $\ell =e,\mu$ decays, and st…
