Search for the rare decay $B^{0} \to J / ψ ϕ$

LHCb collaboration, R. Aaij, C. Abellán Beteta +962

A search for the rare decay $B^{0} \to J / ψ ϕ$ is performed using $pp$ collision data collected with the LHCb detector at centre-of-mass energies of 7, 8 and 13 TeV, correspond…

First branching fraction measurement of the suppressed decay $Ξ_{c}^{0} \to π^{-} Λ_{c}^{+}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +963

The $Ξ_{c}^{0}$ baryon is unstable and usually decays into charmless final states by the $c \to s u d$ transition. It can, however, also disintegrate into a $π^{-}$ meson and a…

Measurement of branching fraction ratios for $B^{+} \to D^{+} D^{-} K^{+}$ , $B^{+} \to D^{-} D^{+} K^{+}$ , and $B^{0} \to D^{*-} D^{0} K^{+}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +914

A measurement of four branching-fraction ratios for three-body decays of $B$ mesons involving two open-charm hadrons in the final state is presented. Run 1 and Run 2 $pp$ collision…
