DESCRIPTION:Petar Maksimovic\, John Hopkins University\n\nIn recent months\
, the Tevatron reached a significant milestone\n and delivered over one&nb
sp\;fb-1 to both the D0 and CDF experiments. The
\n large sample of data and a powerful displaced vertex trigger\n combine
to give CDF the world’s largest sample of fully\n reconstructed Λ\;<
sub>b0s. Using this sample
\, we observe four new\n Λ\;b0
small> π\;+/- resononances\, consistent
with the hypothesis of\n the lowest-lying Σ\;b* baryon states.\n
