Abstract
The SELEX experiment (E781) is a 3-stage magnetic spectrometer for a high s tatistics study of hadroproduction of charm baryons out to large x(F) using 650 GeV Sigma (-),pi (-) and p beams. The main features of the spectromete r are: a high precision silicon vertex system; powerful particle identifica tion provided by TRD and RICH; forward Lambda (s) decay spectrometer; and 3 -stage lead glass photon detector. Preliminary results on asymmetry for Lam bda (c) produced by Sigma (-), pi (-) and p beams at x(F) > 0.2 and precise measurements of the Lambda (c), D-0, and preliminary D-s lifetimes are pre sented.
