英文摘要	We have searched for the cabibbo-suppressed decay lambda(+)(c) -> pi p(0) in e(+) e(-) collisions using a data sample corresponding to an integrated luminosity of 915 fb(-1). the data were collected by the belle experiment at the kekb e(+) e(-) asymmetric-energy collider running at or near the (4s) and (5s) resonances. no significant signal is observed, and we set an upper limit on the branching fraction of b(lambda(+)(c) -> phi p(0)) < 15.3 x 10(-5) at 90% confidence level. the contribution of nonresonant lambda(+)(c) -> k+ k- p pi(0) decays is found to be consistent with zero, and the corresponding upper limit on its branching fraction is set to be b(lambda(+)(c) ->. k+ k- p pi(0))(nr) < 6.3 x 10(-5) at 90% confidence level. we also search for an intermediate hidden-strangeness pentaquark decay p-s(+) -> phi p. we see no evidence for this intermediate decay and set an upper limit on the product branching fraction of b(lambda(+)(c) -> p-s(+) pi(0)) x b(p-s(+) -> phi p) < 8.3 x 10(-5) at 90% confidence level. finally, we measure the branching fraction for the cabibbo-favored decay lambda(+)(c) -> k- pi(+) p pi(0); the result is b(lambda(+)(c) -> k- pi(+) p pi(0)) = (4.42 +/- 0.05(stat)+/- 0.12(syst)+/- 0.16(norm))%, which is the most precise measurement to date.
