Beauty physics with B(s) and Lambda(b) | | R.G.C. Oldeman

21 Jul 2004 | | Subject: | hep-ex | | Abstract: | Although the B(s) and Lambda(b) hadrons differ only in the spectator quarks from the well-studied B(d) and B(u) mesons, they provide a unique window on the physics of the b-quark. With no experiments presently running at the Z pole, hadron colliders now provide the best opportunity to study the B(s) and the Lambda(b). The collider experiments at the Tevatron, CDF and D0, have collected large numbers of B(s) and Lambda(b). Some of their latest preliminary measurements are presented here, including masses, lifetimes, and charmless decays. Progress is made toward measuring the lifetime difference Delta Gamma(s) between the B(s) mass eigenstates and the oscillation frequency Delta m(s). | | Source: | arXiv, hep-ex/0407043 | | Services: | Forum | Review | PDF | Favorites | |
