Beauty production cross section measurements at Ecm=1.96 TeV
  The RunII physics program at the Tevatron started in spring 2001 with protons and antiprotons colliding at an energy of $\sqrt{s}$=1.96 TeV, and it is carrying on with more than 500 pb-1 of data as collected by both the CDF and D0 experiments. Recent results on beauty production cross section measurements are here reported.
