Charm hadroproduction results from Selex

The SELEX experiment (E781) is 5-stage magnetic spectrometer for a high statistics study of hadroproduction of charm baryons out to large x(F) using 650 Gev Sigma (-), pi (-) and p beams. The main features of the spectrometer are: a high precision silicon vertex system, powerful particle identification provided by TRD and RICH, forward Lambda (s) decay spectrometer and 3-stage lead glass photon detector. An experiment overview and spectrometer features are shown. Reconstructed charm states and results on Lambda (c), D+ particles and antiparticles produced by Sigma (-), pi (-) and p beams at x(F) > 0.3 and asymmetry for Lambda (c) are presented
