abstract:
The decay B0 → Λc+ Λc- KS0 is studied at LHCb for the first time using proton-proton collision data recorded by the LHCb experiment at a center-of-mass energy of √s=13 TeV, corresponding to an integrated luminosity of 5.4 fb-1. The branching ratio relative to the decay B+ → Λc+ Λc- K+ is measured to be B(B0 → Λc+ Λc- KS0)/B(B+ → Λc+ Λc- K+) = 0.53 ± 0.05 ± 0.05, where the first uncertainty is statistical and the second is systematic. Evidence is found for contributions from two resonant states, Ξc(2923)+ and Ξc(2939)+, in the Λc+ KS0 system. The two states show a significance of 3.9σ relative to the nonresonant hypothesis. These two Ξc+ states are consistent with being the isospin partners of the states observed in the Λc+ K- system.
