Findings

Measured hadron-nucleus total cross sections around 600 GeV/c.

Deduced sigma_tot(Sigma- N) and sigma_tot(pi- N) from nuclear cross sections.

Provided data relevant for high-energy particle physics models.

Abstract

Total cross sections for Sigma- and pi- on beryllium, carbon, polyethylene and copper as well as total cross sections for protons on beryllium and carbon have been measured in a broad momentum range around 600GeV/c. These measurements were performed with a transmission technique adapted to the SELEX hyperon-beam experiment at Fermilab. We report on results obtained for hadron-nucleus cross sections and on results for sigma_tot(Sigma- N) and sigma_tot(pi- N), which were deduced from nuclear cross sections.
