Production of Strange Secondaries in High Energy Sigma(-)A Collisions

TL;DR

This paper reports experimental data on strange baryon and antibaryon production in high-energy Sigma(-)A collisions and compares it with predictions from the Quark-Gluon String Model.

Contribution

It provides new experimental measurements and evaluates the Quark-Gluon String Model's effectiveness in describing strange baryon production at high energies.

Findings

Model predictions agree with experimental data for certain baryons.

Relations among model parameters are derived using quark combinatorics.

Data enhances understanding of strange particle production in high-energy collisions.

Abstract

We describe the WA89 Collaboration experimental data on Lambda, Sigma(-), Sigma(+), Xi(-), and Omega(-) baryons, and bar(Lambda) and bar(Xi(+)) antibaryons production in Sigma(-) collisions with C and Cu targets at 345 GeV/c (sqrt(s_(Sigma N)) ~ 25.5 GeV) in the frame of the Quark-Gluon String Model. How the theoretical results compare to the experimental data is discussed. Finally, some relations among the values of the model parameters obtained with the help of quark combinatorics are presented.
