Search for the doubly heavy baryons $Ω_{bc}^{0}$ and $Ξ_{bc}^{0}$ decaying to $Λ_{c}^{+} π^{-}$ and $Ξ_{c}^{+} π^{-}$

LHCb collaboration, R. Aaij, C. Abellán Beteta +900

The first search for the doubly heavy $Ω_{bc}^{0}$ baryon and a search for $Ξ_{bc}^{0}$ baryon are performed using $pp$ collision data collected via the LHCb experiment…

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…

Isospin amplitudes in $Λ_{b}^{0} \to J / ψ Λ (Σ^{0})$ and $Ξ_{b}^{0} \to J / ψ Ξ^{0} (Λ)$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +902

Ratios of isospin amplitudes in hadron decays are a useful probe of the interplay between weak and strong interactions, and allow searches for physics beyond the Standard Model. We…
