Abstract

The SELEX experiment (E781) is 3-stage magnetic spectrometer for the study of charm hadroproduction at large xF using 600 Gev Sigma-, pi- and p beams. New precise measurements of the Lambda_c, D0, and Ds lifetimes are presented. We also report results on Lambda_c and Ds production by Sigma-, pi- and p beams at xF>0.2. The data agree with expectations from color-drag models to explain charm particle/antiparticle production asymmetries.Comment: 3 pages, 1 figure.
