Observation of the exotic Y(4140) state by CDF.

Precise measurement of Lambda_b production rates.

Abstract

Using data from proton - antiproton collisions at Ecms = 1.96 TeV recorded by the CDF II and D0 detectors at the Fermilab Tevatron, we present the recent results on charm and bottom hadrons. We report the most recent CDF results on properties of the four bottom baryon resonant states Sigma_b(*)-, Sigma_b(*)+. The new results on exotic Y(4140) state observed by CDF are reported. A precise measurement of production rates of the basic lowest lying bottom baryon Lambda_b produced in the DZero detector is presented.
