Measurements of dihadron correlations triggered by very high-p(T) particles in 2.76 TeV PbPb collisions are presented. The analysis explores the full 2011 PbPb data set corresponding to an integrated luminosity of 150 mu b(-1) collected by CMS. Long-range correlations driven by single-particle azimuthal anisotropies (characterized by the Fourier harmonics, nu(n)) are measured up to p(T) similar to 50 GeV/c. After subtracting the nu(2)-nu(4) harmonic components, the associated particle yields on the near and away side of the residual jet-like dihadron correlations are studied over a wide kinematic range in trigger and associated particle p(T), as a function of collision centrality. By comparing to pp data at the same energy, a suppression of about 50% in the away-side associated yield is observed for p(T)(assoc) > 3GeV/c. The yield is found to be significantly enhanced up to a factor of 3-4 on the away side at p(T)(assoc) similar to 0.5GeV/c. A moderate enhancement is suggested on the near side.
