Study of the $B_{c}^{+}$ decays into charmonia and three light hadrons

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +996

Using proton-proton collision data, corresponding to an integrated luminosity of $9 f b^{- 1}$ collected with the LHCb detector, seven decay modes of the $B_{c}^{+}$ meson into a $J / ψ$ or…

Measurement of the photon polarization in $Λ_{b} \to Λ γ$ decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +994

The photon polarization in $b \to s γ$ transitions is measured for the first time in radiative b-baryon decays exploiting the unique spin structure of $Λ_{b} \to Λ γ$ decays. A data s…
