CDF results on B lifetimes and mixing

B physics, during these years, has become feasible at hadron colliders. Many results are coming from the CDF experiment which runs at the Tevatron collider where protons and antiprotons collide at center-of-mass energy of 1.8 TeV. The CDF detector is described in detail elsewhere. The b production cross section, {sigma}{sub b} {approximately}30{mu}m for {vert_bar}{eta}{vert_bar} < 1, is quite large at the Tevatron, but the total inelastic cross section is about three order of magnitude larger. For this reason the trigger quality is of great importance in order to find B decay products. All B triggers at CDF are based on leptons.
