Findings

Measured cross-sections for secondary particles at various angles and momenta.

Data covers beam momenta from ±3 to ±15 GeV/c.

Results aid in refining nuclear interaction models.

Abstract

We report on double-differential inclusive cross-sections of the production of secondary protons, charged pions, and deuterons, in the interactions with a 5% nuclear interaction length thick stationary copper target, of proton and pion beams with momentum from +/-3 GeV/c to +/-15 GeV/c. Results are given for secondary particles with production angles between 20 and 125 degrees.
