Azimuthal anisotropy in a jet absorption model with fluctuating initial geometry in heavy ion collisions

Abstract

The azimuthal anisotropy due to path-length dependent jet energy loss is studied in a simple jet absorption model that include event by event fluctuating Glauber geometry. Significant anisotropy coefficients v_n are observed for n=1,2 and 3, but they are very small for n>3. These coefficients are expected to result in a "ridge" for correlations between two independently produced jets. The correlations between the orientation of the n^{th}-order anisotropy induced by jet absorption (Φ_n^{QP}) and the n^{th}-order participant plane (Φ_n^{PP}) responsible for harmonic flow are studied. Tight correlations are observed for n=2 in mid-central collisions, but they weaken significantly for n\neq2. The correlations are positive for n>=3, but become negative in central collisions for n>3. The dispersion between Φ_n^{QP} and Φ_n^{PP} is expect to break the factorization of the Fourier coefficients from two-particle correlation v_{n,n} into the single particle v_n, and has important implications for the high-pT ridge phenomena.
