“…In our previous measurements and most RHIC A + A results, the subtracted flow modulations of the underlying event were limited to contributions of v 2 and the fourth-order harmonic component with respect to the second-order event plane v 4 { 2 } [15,16,20,23,28,[44][45][46][47][48]. Only the recent STAR measurement [49] took into account contributions from v 3 and the fourth-order harmonic component uncorrelated to the second-order event-plane in addition to v 4 { 2 }. At low-to-intermediate p T in two-particle correlations, intricate features appear such as the near-side long-range rapidity correlations called the "ridge" [45,50] and the away-side "double-humped" structures [28,44,[46][47][48][49]51,52].…”

“…The experimentally reconstructed second-order harmonic event plane is estimated with charged hadrons from a transverse momentum range of 0.2 < p T < 2.0 GeV/c using the TPC. As described in [9], particles used in the estimation of the event plane are excluded from each associated p T bin used in the azimuthal correlation and jet shape analyses to avoid auto-correlations. Particles within |∆η| = |η − η trig | < R of the trigger jet axis are excluded from the EP determination to help remove non-flow effects from intrajet correlations at high transverse momenta.…”

Jet quenching, which describes the energy lost by jets while interacting with the medium, can be studied using azimuthal correlations of associated hadrons with respect to a trigger jet, and by probing the jet substructure by measuring the differential jet shape. This work will present details of both analyses and explore the impact of a jet's orientation with respect to the event plane, defined by the beam direction and the vector of the impact parameter. This will allow for the study of the path length dependence of medium modifications to the jets and their associated hadrons. Both analyses will reconstruct full (charged + neutral) jets in mid-peripheral Au+Au collisions at √ s NN = 200 GeV with the STAR detector at RHIC.

“…The background has usually been determined using the Zero-Yield-At-Minimum method [19] combined with an assumption that the v n contributions in correlations are the same as those measured independently. The shape of this background when the trigger particle or jet is fixed relative to the second-order event plane was derived in [20] and was used for studies of the path length dependence of partonic energy loss [21,22]. The change in this shape with the angle of the trigger particle relative to the event plane can be used to fit both the background level and shape from the correlations themselves [23]; this method was applied to data in [24].…”

Event plane dependence of the flow modulated background in dihadron and jet-hadron correlations in heavy ion collisions

Di-hadron and jet-hadron correlations are commonly used in relativistic heavy ion collisions to study the soft component of jets in a quark gluon plasma. There is a large correlated background which is described by the Fourier decomposition of the azimuthal anisotropy where vn is the nth order coefficient. The path length dependence of partonic energy loss can be studied by varying the angle of the high momentum trigger particle or jet relative to a reconstructed event plane. This modifies the shape of the background correlated with that event plane. The original derivation of the shape of this background only considered correlations relative to the second order event plane, which is correlated to the initial participant plane. We derive the shape of this background for an event plane at an arbitrary order. There is a phase shift in the case of jets restricted to asymmetric regions relative to the event plane. For realistic correlations between event planes, the correlation between the second and fourth order event planes leads to a much smaller effect than the finite event plane resolution at each order. Finally, we assess the status of the rapidity even v1 term due to flow, which has been measured to be comparable to v2 and v3 terms. 25.75.Gz,25.75.Bh
