dc.description.abstractUsing 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,, and the Cabibbo-favored decay Lambda(+)(c) -> nK(-) pi(+) pi(+) with statistical significances of 7.9 sigma, 7.8 sigma, and > 10 sigma respectively. The branching fractions of these decays are measured to be B(Lambda(+)(c) -> n pi(+)pi(0) ) = (0.64 +/- 0.09 +/- 0.02)%, B(Lambda(+)(c) -> n pi(+)pi(-) pi(+) ) = (0.45 +/- 0.07 +/- 0.03)%, and B(Lambda(+)(c) -> nK(-) pi(+) pi(+)) = (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 Lambda(+)(c) -> n pi(+) pi(0) is about one order of magnitude higher than that of Lambda(+)(c) -> n pi(+).en_US
