Measurements of azimuthal anisotropies of jet production in Pb+Pb collisions at sNN=5.02 TeV with the ATLAS detector

Jet cone radius dependence of $R_{AA}$ and $v_2$ at PbPb 5.02 TeV from JEWEL+$\rm T_RENTo$+v-USPhydro

“…With recoils enabled, R AA increases and v 2 {2} decreases with increasing R, while the opposite is found without the recoiling option, showing the expected anti-correlation between these observables [4]. Additionally, we calculate v 3 {2} for the first time within the JEWEL framework and, for the model without recoils, find a positive triangular flow for R = 0.2 and 71 < p T < 398 GeV jets in 0-5% and 5-10% collisions that is consistent with ATLAS results [42].…”

“…The nuclear modification factor was calculated for jets with |y jet | < 2.8 and transverse momenta between 50 and 630 GeV for 0-10%, 10-20%, 20-30%, 30-40%, 40-50%, and 50-60% centralities, following [77]. The elliptic and triangular anisotropic flow coefficients, expanding on [42], were analyzed for |y jet | < 1.2 and p T in the range of 71 to 650 GeV, with integrated p T bins of 71 to 398 GeV and 200 to 650 GeV, for 0-5%, 5-10%, 10-20%, 20-40%, and 40-60% centralities. Additionally, ratios of R AA were computed for |η jet | < 2.0 and 400 < p T < 500 GeV, centralities of 0-10%, 10-30% and 30-50%, to compare with CMS R-varying measurements [25].…”

“…4. Note that for R AA we use the p T cuts consistent with CMS from [25] whereas, for v 2 {2}, we use the cuts consistent with ATLAS [42]. Our primary motivation for this is to ease comparisons with potential experimental data (other kinematic cuts are available upon request).…”

ATLAS Results on Hard and Electromagnetic Probes in Heavy-Ion Collisions

“…The scalar product method [16] is used to eliminate contributions arising from jets. When compared to similar observables measured for jets [17], the values of v 2 are positive in both cases, even at high p T . However, values of v 3 are consistent with zero, whereas for jets, the positive v 3 values are observed.…”
