Measurement of σΛb0/ σB̄0×B(Λb0→Λc+π-)/B(B̄0→D+π- ) in pp̄ Collisions at s=1.96TeV

Measurement of σΛb0/ σB̄0×B(Λb0→Λc+π-)/B(B̄0→D+π- ) in pp̄ Collisions at s=1.96TeV

We present the first observation of the baryon decay Λb0→ Λc+π- followed by Λc+→pK-π+ in 106pb-1 pp̄ collisions at s=1.96TeV in the CDF experiment. In order to reduce systematic error, the measured rate for Λb0 decay is normalized to the kinematically similar meson decay B̄0→D+π- followed by D+→π+K-...
