Observation of the 0 b → J/ψ−K+ decay

Observation of the 0 b → J/ψ−K+ decay

Abstract Using proton–proton collision data corresponding to an integrated luminosity of 140 fb - 1 collected by the CMS experiment at s = 13 Te V , the Λ b 0 → J / ψ Ξ - K + decay is observed for the first time, with a statistical significance exceeding 5 standard deviations. The relative branching...
