First Observation of Bottom Baryon Sigma_b States at CDF

High Energy Physics - Experiment 2008-11-26 v1

Abstract

We present the latest results on the search of bottom baryon states Sigma_b using 1 fb^-1 of CDF data. The study is performed with the world's largest sample of fully reconstructed Lambda_b decays collected by CDF II detector at the collision energy of 1.96 TeV in the hadronic trigger path. We observe 4 new states consistent with Sigma_b(*)+/- bottom baryons.
