Fluctuation effects in initial conditions for hydrodynamics

摘要

We have studied the fluctuation effects in proton-proton collisions through the analysis of their observables. To investigate the role of fluctuations in initial conditions, we have calculated them using the Interacting Gluon Model modified by the inclusion of the impact parameters, and have applied them to the Landaus's Hydrodynamical Model in one dimension. The rapidity and pseudo-rapidity distributions were calculated using two distinct procedures. One in which we have considered the fluctuations in initial conditions and the other the usual method considering only one fireball with average initial conditions. The obtained results have shown the importance of considering these fluctuations. (author). 25 refs., 5 figs. (Atomindex citation 28:028840)
