Abstract
In parallel to charm hadroproduction the experiment SELEX (E781) at Fermilab is pursuing a rich hyperon physics program. SELEX employs a 600 GeV/c beam consisting of 50% Σ^- and π^- each. The three-stage magnetic spectrometer covering 0.1 <= x_F <= 1.0 features a high-precision silicon vertex system, broad-coverage particle identification using TRD and RICH, and a three-stage lead glass photon calorimeter. First results for the Σ^- charge radius, total (Σ^-)-nucleon cross sections, and a new upper limit for the radiative width of the Σ^-*(1385) are presented.
