First observation of the decay $B_{s 2}^{} (5840)^{0} \to B^{+} K^{-}$ and studies of excited $B_{s}$ mesons

LHCb collaboration, R. Aaij, C. Abellan Beteta +621

Properties of the orbitally excited (L=1) $B_{s}$ states are studied using 1.0 fb $^{- 1}$ of pp collisions at $s = 7$ TeV collected with the LHCb detector. The first observation…

Measurement of $b$ -hadron branching fractions for two-body decays into charmless charged hadrons

LHCb collaboration, R. Aaij, C. Abellan Beteta +589

Based on data corresponding to an integrated luminosity of 0.37 fb^-1 collected by the LHCb experiment in 2011, the following ratios of branching fractions are measured: B(B0 -> pi…

Measurement of the CP-violating phase ϕs in Bs->J/ψπ+π- decays

LHCb collaboration, R. Aaij, C. Abellan Beteta +592

Measurement of the mixing-induced CP-violating phase phi_s in Bs decays is of prime importance in probing new physics. Here 7421 +/- 105 signal events from the dominantly CP-odd fi…
