Using data from the NA32 experiment at CERN we have studied the Λ + c decays containing a Σ + among the decay products. The interactions of 230 GeV π − with a Cu target were analysed using a precise vertex telescope (charge-coupled devices and silicon microstrip detectors) and the ACCMOR spectrometer. We have found eleven Λ + c →Σ + π + π − , one Λ + c →Σ + K + K − , two Λ + c →Σ + K + π − and one Λ + c →Σ + π + π − π + π − decays practically without any backgroun d. We have measured the branching ratios with respect to the Λ + c →pK − π + channel.

Production of the charmed baryon Lambda(c)+ in pi- Cu and K- Cu interactions at 230-GeV

We present results from the NA32 experiment at CERN on the production characteristics of the charmed baryon Λ + c in 230 GeV π − Cu and K − Cu interactions. A high resolution vertex detector consisting of change-coupled devices and silicon microstrip detectors allowed the selection of a very clean sample of 154 Λ + c → pK − π + (and charge conjugate) decays. Results on differential and integrated cross sections are given.
