Observation of the Λ[0 over b] → J/ψ pπ[superscript −] decay
The first observation of the Cabibbo-suppressed decay Λ [0 over b] → J/ψpπ [superscript −] is reported using a data sample of proton-proton collisions at 7 and 8 TeV, corresponding to an integrated luminosity of 3 fb[superscript −1]. A prominent signal is observed and the branching fraction relative...
