Abstract

In the last years it has been revealed that if measuring relative to higher order event planes Ψn, higher order flow coefficients vn for n > 2 can be measured. It also turned out that Bose-Einstein (HBT) correlation radii also show 3rd order oscillations if measured versus the third order event plane Ψ3. In this paper we investigate how these observables can be described via analytic hydro solutions and hydro parameterizations. We also investigate the time evolution of asymmetry coefficients and the mixing of velocity field asymmetries and density asymmetries.
