First evidence for the two-body charmless baryonic decay $B^{0} \to p p ˉ$

LHCb collaboration, R. Aaij, B. Adeva +657

The results of a search for the rare two-body charmless baryonic decays $B^{0} \to p p ˉ$ and $B_{s}^{0} \to p p ˉ$ are reported. The analysis uses a data sample, corresponding t…

Measurement of the fragmentation fraction ratio $f_{s} / f_{d}$ and its dependence on $B$ meson kinematics

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

The relative production rate of $B_{s}^{0}$ and $B^{0}$ mesons is determined with the hadronic decays $B_{s}^{0} \to D_{s}^{-} π^{+}$ and $B^{0} \to D^{-} K^{+}$ . The m…
