Abstract

Based on 4.5 fb−1 e + e − collision data collected with BESIII detector at seven energy points between 4.600 and 4.699 GeV, the branching fractions for Λc+→pη and Λc+→pω were measured by means of single-tag method. The branching fractions of Λc+→pη and Λc+→pω are determined to be (1.57 ± 0.11stat ± 0.04syst) × 10−3 and (1.11 ± 0.20stat ± 0.07syst) × 10−3, with a statistical significance of greater than 10σ and 5.7σ, respectively. These results are consistent with the previous measurements by BESIII, LHCb and Belle, and the result of Λc+→pη is the most precise to date.
