  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.
