title: "Fig. 8 Data Table 12" of "Measurement of the longitudinal flow-plane decorrelation using multi-plane cumulants in $\sqrt{s_{_{\mathrm{NN}}}}$ = 200 GeV Au+Au, Ru+Ru, and Zr+Zr collisions"

description: Centrality dependence of ratio obserbavle $r_{2}$ (Particle-level) vs $r^{ si}_{2}$ (Q-level) for the second-order anisotropic flow in Ru+Ru and Zr+Zr collisions combined.
description: STAR-RHIC. Measurements of the variation of anisotropic flow-plane angles ($\Psi_n$) with rapidity, commonly known as the flow-plane decorrelation, provide important insights into the initial conditions of the matter produced in heavy-ion collisions. In this paper, using data collected by the STAR experiment, we report the first measurement of the four-plane correlator observable $T_{n}\{ba;dc\}=\langle\langle\sin [n(\Psi^{b}_{n}-\Psi^{a}_{n})]\sin[n(\Psi^{d}_{n}-\Psi^{c}_{n})]\rangle\rangle$, where superscripts $a$, $b$, $c$, and $d$ denote sequential pseudorapidity ($\eta$) regions with $a$ corresponding to the most backward region, $b$ and $c$ close to mid-rapidity with $\eta_b&lt;0$ and $\eta_c&gt;0$, and $d$ being the most forward. The measurement is performed for the elliptic and triangular flow (i.e. $n=2$ and $3$) in Au+Au and isobar (Ru+Ru, Zr+Zr) collisions at $\sqrt{s_{_{\mathrm{NN}}}}$ = 200 GeV. The goal of calculating the correlation of the flow-plane angle variations from backward to mid-central, and from mid-central to forward regions, is to probe the systematic variation of flow angle over a wide $\eta$ range. In mid-central collisions ($10-30\%$ centrality), we find $T_{2}\{ba;dc\}= -0.004\pm 0.001 (\rm stat)\pm0.002(\rm syst)$ independent of the collision system. Such a small value of $T_{2}$ favors a “random-walk” variation of the flow-plane angles, where the rapidity correlation length is smaller than the entire region under study. These measurements provide new information on the decorrelation patterns in the system and offer a quantitative estimate of possible systematic variations in anisotropic flow angles such as “twist” between forward and backward regions. This opens new opportunities for understanding the three-dimensional structure and the time evolution of the quark-gluon plasma created in heavy-ion collisions.

title: "Table 1" of "Medium-induced modification of azimuthal correlations of electrons from heavy-flavor hadron decays with charged particles in Pb-Pb collisions at $\sqrt{s_{\rm{NN}} = 5.02}$ TeV"

description: $\Delta\varphi$ correlation distribution between electrons from heavy-flavor hadron decays and associated charged particles for $4 &lt; p_\mathrm{T}^\mathrm{e} &lt; 12$ GeV/$c$ and $1 &lt; p_\mathrm{T}^\mathrm{assoc} &lt; 7$ GeV/c in Pb--Pb collisions at $\sqrt{s_\mathrm{NN}} = 5.02$ TeV in the 0--10% centrality class. The publication shows the correlation distribution for $p_\mathrm{T}^\mathrm{assoc}$ intervals $1 &lt; p_\mathrm{T}^\mathrm{assoc} &lt; 2$, $2 &lt; p_\mathrm{T}^\mathrm{assoc} &lt; 3$, and $5 &lt; p_\mathrm{T}^\mathrm{assoc}&lt; 7$ GeV/$c$. Appendix Figure 1 shows all $p_\mathrm{T}^\mathrm{assoc}$ intervals.
description: The azimuthal-correlation distributions between electrons from the decays of heavy-flavor hadrons and associated charged particles in Pb--Pb collisions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV are reported for the 0--10\% and 30--50\% centrality classes. This measurement provides access to the jet-like correlation observables in the heavy-flavor sector in Pb--Pb collisions. The analysis is performed for trigger electrons from heavy-flavor hadron decays with transverse momentum $4 &lt; p_\mathrm{T}^\mathrm{e} &lt; 16~{\mathrm GeV}/c$, considering associated particles within the transverse-momentum range $1 &lt; p_\mathrm{T}^\mathrm{assoc} &lt; 7$ ${\mathrm GeV}/c$, and a pseudorapidity difference of $|\Delta\eta|&lt;1$ between the trigger electron and associated particles. The per-trigger nuclear modification factor ($I_\mathrm{AA}$) is calculated to compare the near- and away-side peak yields to those in pp collisions at $\sqrt{s} = 5.02$ TeV. In 0--10\% central collisions, the $I_\mathrm{AA}$ indicates a hint of enhancement of associated-particle yields with $p_\mathrm{T}&lt;3$ GeV/$c$ on the near side, and a suppression of yields with $p_\mathrm{T}&gt;4$ GeV/$c$ on the away side. The $I_\mathrm{AA}$ for electron triggers from heavy-flavor hadron decays is compared with that for light-flavor and strange-particle triggers to investigate the dependence on different fragmentation processes and parton-medium dynamics, and is found to be the same within uncertainties.
