- W3185241502 abstract "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 study the new physics sensitivities. We find that the longitudinal dilepton polarization fraction $F_L$ is sensitive to electromagnetic dipole couplings $C_{7}^{(prime)}$, and to the right-handed 4-fermion vector coupling $C_{9}^prime$. The forward-backward asymmetry, $A_{rm FB}$, due to the GIM-suppression a standard model null test already, probes the left-handed axialvector 4-fermion coupling $C_{10}$; its CP-asymmetry, $A_{rm FB}^{rm CP}$, probes CP-violating phases in $C_{10}$. Physics beyond the standard model can induce branching ratios of dineutrino modes $Lambda_c to p nu bar nu $ up to a few times $10^{-5}$, and one order of magnitude smaller if lepton flavor universality is assumed, while standard model rates are negligible. Charged lepton flavor violation allows for striking signals into $e^pm mu^mp$ final states, up to $10^{-6}$ branching ratios model-independently, and up to order $10^{-8}$ in leptoquark models. Related three-body baryon decays $Xi_c to Sigma ell ell$, $Xi_c to Lambda ell ell$ and $Omega_c to Xi ell ell$ offer similar opportunities to test the standard model with $|Delta c|=|Delta u|=1$ transitions." @default.
