First observation of the decays $B ˉ_{(s)}^{0} \to D_{s}^{+} K^{-} π^{+} π^{-}$ and $B ˉ_{s}^{0} \to D_{s 1} (2536)^{+} π^{-}$

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

The first observation of the decays $B ˉ_{s}^{0} \to D_{s}^{+} K^{-} π^{+} π^{-}$ and $B ˉ^{0} \to D_{s}^{+} K^{-} π^{+} π^{-}$ are reported using an integrated luminosity of 1.0 fb $^{- 1}$ recorded by the…

Measurement of transparency ratios for protons from short-range correlated pairs

O. Hen, H. Hakobyan, R. Shneor +5

Nuclear transparency, Tp(A), is a measure of the average probability for a struck proton to escape the nucleus without significant re-interaction. Previously, nuclear transparencie…

Measurement of J/psi production in pp collisions at sqrt(s)=2.76 TeV

LHCb collaboration, R. Aaij, C. Abellan Beteta +624

The production of J/psi mesons is studied with the LHCb detector using data from pp collisions at sqrt(s)=2.76 TeV corresponding to an integrated luminosity of 71 nb^-1. The differ…

Evidence for the decay $B^{0} \to J / ψ ω$ and measurement of the relative branching fractions of $B_{s}^{0}$ meson decays to $J / ψ η$ and $J / ψ η^{^{'}}$

LHCb Collaboration, R. Aaij, C. Abellan Beteta +620

First evidence of the $B^{0} \to J / ψ ω$ decay is found and the $B_{s}^{0} \to J / ψ η$ and $B_{s}^{0} \to J / ψ η^{'}$ decays are studied using a dataset corresponding to an integrated lumino…

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…
