Abstract
We present measurements of the scale (bin-size) dependence of event-wise mean transverse momentum ãptã fluctuations for Au-Au collisions at sNN=200GeV simulated with the Hijing-1.37 Monte Carlo. We invert those scale distributions to obtain autocorrelation distributions on pseudorapidity η and azimuth Ï difference variables (ηÎ,ÏÎ). The autocorrelations have a simple structure dominated by a same-side (on azimuth) peak with similar widths on the two difference variables. With jet quenching imposed, the same-side peak widths increase slightly in both directions, and the amplitude is substantially reduced. The same-side peaks are attributed to minijets, observed in this study as local velocity correlations of charged particles with pt<2GeV/c.
