    "abstract": "The methods currently used to measure collective flow in nucleus--nucleus\ncollisions assume that the only azimuthal correlations between particles are\nthose arising from their correlation with the reaction plane. However, quantum\nHBT correlations also produce short range azimuthal correlations between\nidentical particles. This creates apparent azimuthal anisotropies of a few\npercent when pions are used to estimate the direction of the reaction plane.\nThese should not be misinterpreted as originating from collective flow. In\nparticular, we show that the peculiar behaviour of the directed and elliptic\nflow of pions observed by NA49 at low p_T can be entirely understood in terms\nof HBT correlations. Such correlations also produce apparent higher Fourier\nharmonics (of order n larger than 3) of the azimuthal distribution, with\nmagnitudes of the order of 1%, which should be looked for in the data.",
