Ways to constrain the away side jet in Au + Au collisions in PHENIX

Abstract

We discussed methods used by the PHENIX to constrain the flow background in the two particle jet correlation. Both the background level and elliptic flow can be reliably decomposed from the jet contribution. We also studied the non-flow contribution to the reaction plane elliptic flow due to dijets. We found the jet bias is negligible in PHENIX, when the reaction plane is measured at Beam Beam Counter acceptance ($3<|\eta |<4$).
