Abstract

This paper presents data on the emission of helium fragments due to break up of 200 A GeV 32S ions in collision with emulsion nuclei. A total of 499 minimum bias events have been studied in an emulsion stack and 97 events in emulsion chambers. Emission angles of He fragments have been measured with high precision. This data has been compared with data of breakup of heavier as well as lighter projectiles and we observe that the value of the momentum spread, σ(p), increases with increasing projectile mass. The bulk part of the helium emission is consistent with a single source for helium fragments with an average excitation energy of (9.1±0.9) MeV. A tail of a few (

Abstract

In this letter we show that most of the fluctuations in particle densities observed in relativistic heavy-ion collisions are consistent with stochastic emission, i.e., most of the correlations between produced particles are washed out due to the vast number of particles in the environment. We further explore the general trends by investigating different systems, energies and centrality cuts. Comparisons with the Fritiof model show that string fragmentation gives results similar to the data.
