Abstract

The proton rapidity distributions in nucleus-nucleus collisions at the Alternating Gradient Synchrotron (AGS) and the Super Proton Synchrotron (SPS) energies are analyzed by the revised thermalized cylinder model. The calculated results are compared and found to be in agreement with the experimental data of Si-Al and Si-Pb collisions at 14.6 AGeV/c, Pb-Pb collisions at 158 AGeV/c, and S-S collisions at 200 AGeV/c.

Keywords: Proton rapidity distribution; nucleus-nucleus collisions; high energy.

 

Resumen

La rapidez de distribución de protones en colisiones nucleo-nucleo en las energías de sincrotron de gradiente alternante (AGS) y sincrotron de super proton (SPS) es analizada usando el modelo del cilindro termalizado. Los resultados calculados al ser comparados con los resultados experimentales están en concordancia con las colisiones de Si-Al y Si-Pb a 14.6 AGeV/c, Pb-Pb a 158 AGeV/c y S-S a 200 AGeV/c.

Palabras clave: Rapidez de distribución de protones; colisiones nucleo-nucleo; alta energía.

PACS: 25.75.-q; 25.75.Dw; 24.10.Pa
