Abstract

STAR measurements of dihadron correlations with high-pt trigger partcles in Au+Au collisions at 200 GeV are presented with subtraction of v2, v3, and v4 backgrounds. The vn azimuthal anisotropies were measured by the two-particle cumulant method with η gap to reduce nonflow. The dihadron correlations relative to the v2 as well as the v3 harmonic planes are also presented. Implications of the results are discussed.
