Jet quenching and event-wise mean-pt fluctuations in Au-Au collisions at sqrt-sNN = 200 GeV in Hijing-1.37

Based on Hijing-1.37 simulations, event-wise mean-pt fluctuations in Au-Au collisions at sqrt-sNN = 200 GeV are studied with graphical and numerical methods. This study shows that jets/minijets could represent a substantial source of mean-pt fluctuations, and jet quenching could reduce these fluctuations significantly. Mean-pt fluctuation measurements are a promising probe of correlation structure produced in the early stages of central collisions at RHIC energies.
