Observation of J/ψp resonances consistent with pentaquark states in Λ0b→J/ψK-p decays

Observations of exotic structures in the J/ψp channel, which we refer to as charmonium-pentaquark states, in Λ0b→J/ψK−p decays are presented. The data sample corresponds to an integrated luminosity of 3 fb−1 acquired with the LHCb detector from 7 and 8 TeV pp collisions. An amplitude analysis of the...
