【 摘 要 】

We report the first measurements of azimuthal anisotropy at midrapidity originated from the dipole asymmetry due to uctuations in the initial geometry in Au+Au collisions at √sNN = 200 GeV, based on data from the STAR experiment at the Relativistic Heavy Ion Collider. The signal is almost symmetric in pseudorapidity and we report it as a function of pseudorapidity and transverse momentum for different centrality. Results are compared with available model predictions.
