Abstract
Measurements of the variation of inclusive jet suppression as a function of relative azimuthal angle, , with respect to the elliptic event plane provide insight into the path-length dependence of jet quenching. ATLAS has measured the dependence of jet yields in of collisions at the LHC for jet transverse momenta in different collision centrality bins using an underlying event subtraction procedure that accounts for elliptic flow. The variation of the jet yield with was characterized by the parameter, , and the ratio of out-of-plane () to in-plane () yields. Nonzero values were measured in all centrality bins for . The jet yields are observed to vary by as much as 20% between in-plane and out-of-plane directions.
