New Results on Bottom Baryons with the CDF II Detector
Abstract
We present measurements of the masses and widths of four bottom baryon resonances, Sigmab(*)+-, reconstructed in the Lambdab pi+- hadron decay modes. The isospin mass splittings for the Sigmab and Sigmab* multiplets are extracted as well. The analysis is based on a data sample corresponding to an integrated luminosity of 6 fb-1 .
