Cross-Sections of Large-Angle Hadron Production in Proton- and Pion-Nucleus Interactions V: Lead Nuclei and Beam Momenta from +/-3 Gev/c to +/-15 Gev/c

TL;DR

This paper presents detailed measurements of secondary particle production cross-sections in proton and pion interactions with lead nuclei across a range of beam momenta, angles, and compares these with other target materials.

Contribution

It provides new double-differential cross-section data for secondary particles produced in proton and pion lead interactions over a wide momentum and angular range.

Findings

Cross-sections vary with beam momentum and particle type.

Comparison shows differences between lead and lighter or heavier nuclei.

Data can improve 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 lead 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 20 to 125 degrees. Cross-sections on lead nuclei are compared with cross-sections on beryllium, copper, and tantalum nuclei.
