Model-independent evidence for $J/\psi p$ contributions to ${\Lambda }_b^0\to J/\psi p{K}^{-}$ decays

LHCb collaboration, R. Aaij, C. Abellán Beteta +731

The data sample of ${\Lambda }_b^0\to J/\psi p{K}^{-}$ decays acquired with the LHCb detector from 7 and 8~TeV $pp$ collisions, corresponding to an integrated luminosity of 3 fb${}^{-1}$, is inspect…
