FIG. 4. Ridge yield Eq. (9) in $|\Delta \eta|<1.7$ and $2 \mathrm{GeV/c}<p^{assoc}_{t}$ < $p^{trig}_{t}$ as a function of $p_{t}^{t r i g}$. Solid lines are the systematic uncertainty due to $v_{2}$.

FIG. 5. Projection of $d N /\left.d \Delta \phi\right|_{a, b}$ for $0.7<|\Delta \eta|<1.4$ [Eq. (3)] in two trigger $p_{t}$ windows for $2<p_{t}^{\text {assoc }}<4 \mathrm{GeV} / \mathrm{c} .$ No background subtraction has been applied; note the suppressed zero on the vertical scale. The shaded band shows the fit of the function $k_{1}+k_{2}$. $\cos (2 \Delta \phi)$ to the recoil region $2<|\Delta \phi|<\pi$ for $4<p_{t}^{\text {trig }}<6 \mathrm{GeV} / c$. The width of the band indicates the fitting error. The solid curve represents the background estimate using the ZYAM normalization for $4<p_{t}^{\text {trig }}<6 \mathrm{GeV} / c .$ Systematic uncertainties are indicated by the light shaded band.

FIG. 6. (Color online) Differential $p_{t}$ spectrum for associated particles in central $\mathrm{Au}+$ Au collisions, with $4<p_{t}^{\text {trig }}<6$ and $6<p_{t}^{\text {trig }}<10 \mathrm{GeV} / c$ . The dash-dotted line is the inclusive hadron spectrum from central $\mathrm{Au}+$ Au collisions $[1] .$ Left panel: ridge spectrum; shaded bands show systematic uncertainty. Right panel: jet-like spectrum, also compared to $d+$ Au reference measurements. The lines in both panels show exponential fits to the data (see Table III). Data are offset horizontally for clarity.
