A peak in the pK-+ and p»K+- invariant-mass spectra at 2.2850.006 GeV/c2 is observed, which is associated with the lowest-lying charmed baryon (c). A cross section times branching ratio of 0.0370.012 nb at Ec.m.=5.2 GeV is measured with a substantial fraction of the events produced with an equal recoiling mass. New measurements of inclusive p and cross sections are also presented, allowing an estimate of the branching ratio B(c+pK-+)=0.0220.010. © 1980 The American Physical Society.
