"Discovery of Σb"
 Slideshow (PDF)
In recent months, the Tevatron reached a significant milestone and delivered over one fb-1 to both the D0 and CDF experiments. The large sample of data and a powerful displaced vertex trigger combine to give CDF the world’s largest sample of fully reconstructed Λb0s. Using this sample, we observe four new Λb0 π+/- resononances, consistent with the hypothesis of the lowest-lying Σb* baryon states.
