Title: Reexamining the iconic dihadron correlation measurement demonstrating jet quenching

Abstract

We report that early measurements at the BNL Relativistic Heavy Ion Collider (RHIC) demonstrated jet quenching through the suppression of pairs of high momentum hadrons. These dihadron correlations have a large correlated background. As understanding of the background improved, it was recognized in the field that a significant term was omitted from the background and several dihadron correlation results were quantitatively and qualitatively incorrect. The original measurements demonstrating jet quenching have not been revisited. These measurements are repeated in this paper in a kinematic range similar to the original measurement using publicly available data, applying current knowledge about the background. Finally, the new results are qualitatively consistent with the previous results, demonstrating complete suppression of the away side within uncertainties.
