The sample corresponds to an integrated luminosity of 567 pb(-1). The branching fraction is determined to be B( Lambda(+)(c) -> Lambda mu(+)nu(mu)) = (3.49 +/- 0.46( stat) +/- 0.27( syst))%. In addition, we calculate the ratio B( Lambda(+)(c) -> Lambda mu(+)nu(mu))/B(Lambda(+)(c) -> Lambda e(+)nu(e) to be 0.96 +/- 0.16( stat) +/- 0.04( syst).eninfo:eu-repo/semantics/openAccessAstronomy & astrophysicsPhysicsLambda(+)(c)Semi-leptonic decayAbsolute branching fractionBESIIISemileptonic decaysBaryon decaysCharm baryonsPredictionsArticle0003978617000082-s2.0-850111027234247767Astronomy & astrophysicsPhysics, nuclearPhysics, particles & fieldsDeterioration; Elementary Particles; Octets
