Abstract
We present the first observation of the baryon decay followed by in collisions at in the CDF experiment. In order to reduce systematic error, the measured rate for decay is normalized to the kinematically similar meson decay followed by . We report the ratio of production cross sections () times the ratio of branching fractions () for the momentum region integrated above and pseudorapidity range : .
