title: "Figure 1d " of "Indications of Conical Emission of Charged Hadrons at RHIC"

description: FIG. 1: (a) Raw two-particle correlation signal $Y_2$ (red), background $aB_{inc}F_2$ (solid histogram), and background systematic uncertainty from a (dashed histograms). (b) Background-subtracted two-particle correlation $\hat{Y}_2$ (red), and systematic uncertainties due to a (dashed histograms) and flow (blue histograms). (c) Raw three-particle correlation $Y_3$. (d) $ba^2Y_{inc}^2$ . (e) Sum of trig-corr-bkgd and trigger flow. Data are from 12% central Au+Au collisions. Statistical errors in (a,b) are smaller than the point size.
description: Three-particle azimuthal correlation measurements with a high transverse momentum trigger particle are reported for pp, d+Au, and Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV by the STAR experiment. Dijet structures are observed in pp, d+Au and peripheral Au+Au collisions. An additional structure is observed in central Au+Au data, signaling conical emission of correlated charged hadrons. The conical emission angle is found to be $\theta$ = 1.37 $\pm$ 0.02(stat)$^{+0.06}_{−0.07}$(syst), independent of p$_\perp$.

NOTE: For points with invisible error bars, the point size was considered as an absolute upper limit for the uncertainty.

description: FIG. 1: a) left side: The $\Delta\phi$ - $\Delta\eta$ correlation data for unlike-sign charge particle pairs from the Star central trigger dataset shown in a 2-dimensional (2-D) perspective plot. The particle tracks have 0.8 GeV/c &lt; $p_t$ &lt; 2.0 GeV/c and |$\eta$| &lt; 1.0. The structure that looks like tiles on a roof is due to the readout boundary effects of the 12 sector TPC. b) right side: The similar correlation data for like-sign charge particle pairs is shown.
description: We report charged-particle pair correlation analyses in the space of ∆φ (azimuth) and ∆η (pseudorapidity), for central Au + Au collisions at $\sqrt{s_{NN}}$ = 200 GeV in the STAR detector. The analysis involves unlike-sign charge pairs and like-sign charge pairs, which are transformed into chargedependent (CD) signals and charge-independent (CI) signals. We present detailed parameterizations of the data. A model featuring dense gluonic hot spots as first proposed by Van Hove predicts that the observables under investigation would have sensitivity to such a substructure should it occur, and the model also motivates selection of transverse momenta in the range 0.8 &lt; $p_t$ &lt; 2.0 GeV/c. Both CD and CI correlations of high statistical significance are observed, and possible interpretations are discussed.
