Zimányi Winter School, 2013/12/05 Csörgő, T. 5 Directed, elliptic and other flows Directed, elliptic and other flows Note: model is fully analytic As of now, only X = Z = R(t) spheroidal solutions are found → vanishing odd order flows See next talk for fluctuations From the single particle spectra → flow coefficents v n

Zimányi Winter School, 2013/12/05 Csörgő, T. 11 Summary Summary Observables calculated Effects of rotation and flow Combine and have same mass dependence Spectra: slope increases v 2 : universal w scaling remains valid HBT radii: Decrease with mass intensifies Even for spherical expansions: v 2 from rotation.
