Abstract: (arXiv)

We report the first three-particle coincidence measurement in pseudorapidity (

\Delta\eta

) between a high transverse momentum (

p_{\perp}

) trigger particle and two lower

p_{\perp}

associated particles within azimuth

+Au and Au+Au collisions. Charge ordering properties are exploited to separate the jet-like component and the ridge (long-range

\Delta\eta

correlation). The results indicate that the particles from the ridge are uncorrelated in

\Delta\eta

not only with the trigger particle but also between themselves event-by-event. In addition, the production of the ridge appears to be uncorrelated to the presence of the narrow jet-like component.
