Observation of the Omega_b^- and Measurement of the Properties of the Xi_b^- and Omega_b^-

CDF Collaboration, T. Aaltonen

We report the observation of the bottom, doubly-strange baryon Omega^-_b through the decay chain Omega^-_b -> J/psi Omega^-, where J/psi -> mu^+ mu^-, Omega^- -> Lambda K^-, and La…
