Abstract

The inclusive production of charmed baryonsΛc+ by 40–70 GeV neutrons on carbon has been observed. The decays\(\Lambda _c^ + \to \bar K^0 p\pi ^ + \pi ^ -\) (130 ± 18 events) andΛc+→Λ0π+π+π− (57±14 events) have been detected. The mean value ofΛc+ mass is (2,268±6) MeV/c2. The invariant cross section forX>0.5 is described byE·d3σ/dp3∝ exp(−)bPT·(1−X)n withb=(2.5±0.6) (GeV/c)−1 andn=(1.5±0.5).
