The geometrical overlap region in non-central heavy ion collisions is almond shaped. Due to this shape profile, density fluctuations for different harmonics are strongly correlated; for example v1 and v3. If the final momentum space distributions in heavy-ion collisions depend on the initial density, then the coupling of different harmonics will lead to three particle correlations such as cos(phi_1+2phi_2-3phi_3). In this poster we present STAR measurements of cos(phi_1+2phi_2-3phi_3) as a function of pt and centrality in $\sqrt{s_{NN}}$ = 200 GeV Au+Au collisions. We compare our results to predictions from Teaney and Yan (1) based on ideal hydrodynamic calculations. (1) D. Teaney and L. Yan, arXiv:1010.1876v1 [nucl-th]
