Abstract:
The measurement of anisotropic flow in heavy-ion collisions gives insight into the equation of state of the matter formed in the collision. Several methods are available for measuring anisotropic flow. However, methods based on two-particle correlations do not reproduce the flow signal if nonflow is present. Methods based on multi-particle correlations do. A new reaction plane estimate is presented based on the Lee-Yag zeroes method, that enables an unbiased analysis of e.g. jets ofr charm versus the reaction plane.
