    "abstract": "Elliptic flow systematics for different hadron species have been explained by\nquark coalescence models. It has been argued that the elliptic asymmetry v_2\nshould scale with the number of quarks that comprise the hadron. We show how\nthese arguments are sensitive to the relative role of asymmetries in the phase\nspace density vs. asymmetries in the effective volume of emission. We also\ndiscuss the degree to which coalescence arguments differ from thermal models.\nIllustrative calculations based on solving the Boltzmann equation are presented\nalong with the results of blast-wave models. Although the issue is complicated,\nambiguities might be clarified by measurements of source-size parameters for\nnucleons at higher transverse momenta.",
