Abstract

Using data collected by the CLEO detector in the γ(4S) region, we report new measurements of the exclusive decays of B mesons into final states of the type Λ c +p̄n(π), where n= 0,1,2,3. We find signals in modes with one, two and three pions and an upper limit for the two-body decay Λ c +p̄. We also make the first measurements of exclusive decays of B mesons to ∑ cp̄n(π), where n = 0,1,2. We find signals in modes with one and two pions and an upper limit for the two-body decay ∑ cp̄. Measurements of these modes shed light on the mechanisms involved in B decays to baryons.
