BABAR Collaboration; Lees, J P; Poireau, V; Tisserand, V; Snoek, H L; et al (2012). Search for B̅ →Λc+Xℓ-ν̅ ℓ decays in events with a fully reconstructed B meson. Physical Review D (Particles, Fields, Gravitation and Cosmology), 85(1):011102.
We present a search for semileptonic B decays to the charmed baryon Λc+ based on 420 fb-1 of data collected at the Υ(4S) resonance with the BABAR detector at the PEP-II e+e- storage rings. By fully reconstructing the recoiling B in a hadronic decay mode, we reduce non-B backgrounds and determine the flavor of the signal B. We statistically correct the flavor for the effect of the B0 mixing. We obtain a 90% confidence level upper limit of B(B̅ →Λc+Xℓ-ν̅ ℓ)/B(B̅ →Λc+X)<3.5%.
