Charmed Λc+ baryons fully reconstructed in the pK−π+, pK0S, and Λπ+π+π− modes, are associated to a lepton with opposite charge in order to select Image decays. From a combined likelihood and event rate fit to the distribution of the IsgurWise variable w, and using the Heavy Quark Effective Theory (HQET), the slope of the b-baryon form factor is measured to be Image The exclusive semileptonic branching fraction Image can be derived from Image and is found to be (5.0+1.1−0.8(stat)+1.6−1.2(syst))%. Limits on other branching fractions are also obtained.
