【摘要】 Using electron-positron annihilation data samples corresponding to an integrated luminosity of 4.5 fb-1,collected by the BESⅢ detector in the energy region between 4599.53 MeV and 4698.82 MeV,we report the first observations of the Cabibbo-suppressed decays Λc+→nπ+π0,Λc+→nπ+π-π+,and the Cabibbo-favored decayΛc+→nK-π+π+ with statistical significances of 7.9σ,7.8σ,and >10σ,respectively.The branching fractions of these decays are measured to be B(Λc+→nπ+π0)=(0.64±0.09±0.02)%,B(Λc+→nπ+π-π+)=(0.45±0.07±0.03)%,and B(Λc+→nK-π+π+)=(1.90±0.08±0.09)%,where the first uncertainties are statistical and the second are systematic.We find that the branching fraction of the decay Λc+→nπ+π0 is about one order of magnitude higher than that of Λc+→nπ+.更多还原
