### Measurement of sigma Lambda b0/sigma B0 x B(Lambda b0--&gt;Lambda c+pi-)/B(B0--&gt;D+pi-) in pp collisions at square root s=1.96 TeV.

Abstract:

We present the first observation of the baryon decay Lambda b0-->Lambda c+pi- followed by Lambda c+-->pK-pi+ in 106 pb-1 pp collisions at square root s=1.96 TeV in the CDF experiment. In order to reduce systematic error, the measured rate for Lambda b0 decay is normalized to the kinematically similar meson decay B0-->D+pi- followed by D+-->pi+K-pi+. We report the ratio of production cross sections (sigma) times the ratio of branching fractions (B) for the momentum region integrate...
