Based on 586 pb−1 of e+e− annihilation data collected at a center-of-mass energy of s=4.6GeV with the BESIII detector at the BEPCII collider, the absolute branching fraction of Λc+→pKS0η decays is measured for the first time to be B(Λc+→pKS0η)=(0.414±0.084±0.028)%, where the first uncertainty is statistical and the second is systematic. The result is compatible with a previous CLEO result on the relative branching fraction [Formula-presented], and consistent with theoretical predictions of SU(3) flavor symmetry.

Abstract

Based on 586 pb−1 of e+e− annihilation data collected at a center-of-mass energy of s=4.6GeV with the BESIII detector at the BEPCII collider, the absolute branching fraction of Λc+→pKS0η decays is measured for the first time to be B(Λc+→pKS0η)=(0.414±0.084±0.028)%, where the first uncertainty is statistical and the second is systematic. The result is compatible with a previous CLEO result on the relative branching fraction [Formula-presented], and consistent with theoretical predictions of SU(3) flavor symmetry.
