Abstract
A peak in the and invariant-mass spectra at 2.285±0.006 GeV/ is observed, which is associated with the lowest-lying charmed baryon (). A cross section times branching ratio of 0.037±0.012 nb at GeV is measured with a substantial fraction of the events produced with an equal recoiling mass. New measurements of inclusive and cross sections are also presented, allowing an estimate of the branching ratio .
