Abstract

We present the directed flow (v₁) measured in Au+Au collisions at √s_NN=62.4 GeV in the midpseudorapidity region |\ensuremathη|<1.3 and in the forward pseudorapidity region 2.5<|\ensuremathη|<4.0. The results are obtained using the three-particle cumulant method, the event plane method with mixed harmonics, and for the first time at the Relativistic Heavy Ion Collider, the standard method with the event plane reconstructed from spectator neutrons. Results from all three methods are in good agreement. Over the pseudorapidity range studied, charged particle directed flow is in the direction opposite to that of fragmentation neutrons.
