Hyperon Physics Results from Selex

Ivo Eschrich, Max Planck Institute for Nuclear Physics, Heidelberg

In parallel to charm hadroproduction the experiment SELEX (E781) at Fermilab is pursuing a rich hyperon physics program.

SELEX employs a 600 GeV/c high-intensity tex2html_wrap_inline11 beam and a three-stage magnetic spectrometer covering tex2html_wrap_inline13. The spectrometer 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 tex2html_wrap_inline15 charge radius, total tex2html_wrap_inline15 - nucleon cross sections, and a new upper limit for the radiative width of the tex2html_wrap_inline19 are presented.
