Resumen/Abstract
Using data from pp̅ collisions at √s=1.96  TeV recorded by the CDF II detector at the Fermilab Tevatron, we present improved measurements of the masses and first measurements of natural widths of the four bottom baryon resonance states Σb+, Σb*+ and Σb-, Σb*-. These states are fully reconstructed in their decay modes to Λb0π± where Λb0→Λc+π- with Λc+→pK-π+. The analysis is based on a data sample corresponding to an integrated luminosity of 6.0  fb-1 collected by an online event selection based on tracks displaced from the pp̅ interaction point.
