摘要:We describe the origins of hpt i fluctuations in terms of local pt spectrum shape changes on (h,f ).
We review fluctuation measure design and hpt i fluctuation measurements at the SPS and RHIC.
We show that pt angular autocorrelations derived from the scale dependence of hpt i fluctuations
reveal a complex parton scattering and dissipation process in RHIC heavy ion collisions. From
pt correlation structure in heavy ion collisions we observe for the first time temperature/velocity
structure resulting from copious low-Q2 parton scattering. We also observe novel structure which
could result from collective bulk-medium recoil in response to parton stopping. The energy dependence
of hpt i fluctuations is strong and consistent with QCD energy trends.
