A novel measurement of Bs0B^0_s and Ds−D^-_s lifetimes using semileptonic decays at LHCb

I report new, world-leading LHCb results on heavy meson lifetimes. We use a novel approach that suppresses the shortcomings typically associated with reconstruction of semileptonic decays, allowing for precise measurements of lifetimes and other properties in collider experiments. We achieve a 15% and a $2\times$ improvement over current best determinations of the flavor-specific $B^0_s$ lifetime and $D^-_s$ lifetime, respectively.Comment: 12 pages, 6 figures.

CDF Hot Topics

After an introduction on the peculiarities of flavor-physics measurements at a hadron collider, and on the upgraded Collider Detector at Fermilab (CDF II), I show recent results on two-body B0 and B0s decays into charged, pseudo-scalar, charmless mesons or into muons, to illustrate how the flavor physics program at CDF is competitive with (in B0 decays) and complementary (in B0s decays) to B-factories. Results shown include the new measurement of the CP-violating asymmetry in B0-->K+pi- decays, the first measurement of the time-evolution of B0s-->K+K- decays, and the world best limits on the decay rates of rare B0/B0s-->mu+mu- modes.Comment: write-up for the proceedings of the "Flavor Physics & CP Violation Conference, Vancouver, 2006". 9 pages, 10 figures, to be published in the Electronic Conference Proceedings Archiv
