SEMINAR      Wednesday, 19 April 2006 - h. 15:00 Auditorium B. Touschek    Giovanni Punzi (Università di Pisa) B physics and Bs mixing results at the Tevatron Abstract The run II at Tevatron has recently reached 1 fb-1 of integrated luminosity. In the meantime a program to further increase the luminosity is successfully under way. This has allowed the experiments CDF and D0 to obtain new interesting results concerning also the B-hadrons, especially the very recent and important measurements on Bs oscillations. These results lead to further speculations on future opportunities of B physics in hadron collisions.
