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…

Study of $D_{s J}$ decays to $D^+\KS$ and $D^{0} K^{+}$ final states in $pp$ collisions

LHCb collaboration, R. Aaij, C. Abellan Beteta +616

A study of $D^+\KS$ and $D^{0} K^{+}$ final states is performed in a sample of 1.0/fb of $pp$ collision data collected at a centre-of-mass energy of $s = 7$ TeV with the \lhcb dete…

Measurement of the effective $B_{s}^{0} \to K^{+} K^{-}$ lifetime

LHCb collaboration, R. Aaij, C. Abellan Beteta +616

A precise determination of the effective $B_{s}^{0} \to K^{+} K^{-}$ lifetime can be used to constrain contributions from physics beyond the Standard Model in the $B_{s}^{0}$ meson sys…

Measurement of the CP violating phase ϕ_s in Bs->J/ψf0(980)

LHCb Collaboration, R. Aaij, C. Abellan Beteta +585

Measurement of mixing-induced CP violation in Bs decays is of prime importance in probing new physics. So far only the channel Bs->J/ψϕ has been used. Here we report on a measureme…
