英文摘要	We report on the first measurement of the azimuthal anisotropy (v(2)) of dielectrons (e(+)e(-) pairs) at mid-rapidity fromv root s(NN) = 200 GeV Au + Au collisions with the STAR detector at the Relativistic Heavy Ion Collider (RHIC), presented as a function of transverse momentum (pT) for different invariant-mass regions. In the mass region M-ee < 1.1 GeV/c(2) the dielectron v(2) measurements are found to be consistent with expectations from pi(0), eta, omega, and phi decay contributions. In the mass region 1.1 < M-ee < 2.9 GeV/c(2), the measured dielectron v(2) is consistent, within experimental uncertainties, with that from the c<(c)over bar> contributions.
