Özet
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 Lambda(+)(c)-> p eta and Lambda(+)(c)-> p omega were measured by means of single-tag method. The branching fractions of Lambda(+)(c)-> p eta and Lambda(+)(c)-> p omega are determined to be (1.57 +/- 0.11(stat) +/- 0.04(syst)) x 10(-3) and (1.11 +/- 0.20(stat) +/- 0.07(syst)) x 10(-3), with a statistical significance of greater than 10 sigma and 5.7 sigma, respectively. These results are consistent with the previous measurements by BESIII, LHCb and Belle, and the result of Lambda(+)(c)-> p eta is the most precise to date.
