dc.description.abstractBased on 4.5 fb(-1 )data taken at seven center-of-mass energies ranging from 4.600 to 4.699 GeV with the BESIII detector at the BEPCII collider, we measure the branching fractions of Lambda(+)(c) ->Sigma(+) + hadrons relative to Lambda(+)(c) ->Sigma(+)pi(+)pi(-). Combining with the world average branching fraction of Lambda(+)(c) ->Sigma(+)pi(+)pi(-), their branching fractions are measured to be (0.377 +/- 0.042 +/- 0.020 +/- 0.021)% for Lambda(+)(c) ->Sigma+K+K-, (0.200 +/- 0.023 +/- 0.011 +/- 0.011)% for Lambda(+)(c) ->Sigma K-+(+)pi(-), (0.414 +/- 0.080 +/- 0.030 +/- 0.023)% for Lambda(+)(c) ->Sigma(+)phi and (0.197 +/- 0.036 +/- 0.009 +/- 0.011)% for Lambda(+)(c) ->Sigma+K+K-(non-phi). In all the above results, the first uncertainties are statistical, the second are systematic and the third are from external input of the branching fraction of Lambda(+)(c) ->Sigma(+)pi(+)pi(-). Since no signal for Lambda(+)(c) ->Sigma K-+(+)pi(-)pi(0) is observed, the upper limit of its branching fraction is determined to be 0.13% at the 90% confidence level.en_US
