    abstract = "First measurements of dihadron correlations for charged particles are
presented for central PbPb collisions at a nucleon-nucleon
center-of-mass energy of 2.76 TeV over a broad range in relative
pseudorapidity (Delta eta) and the full range of relative azimuthal
angle (Delta phi). The data were collected with the CMS detector, at the
LHC. A broadening of the away-side (Delta phi approximate to pi)
azimuthal correlation is observed at all Delta eta, as compared to the
measurements in pp collisions. Furthermore, long-range dihadron
correlations in Delta eta are observed for particles with similar phi
values. This phenomenon, also known as the “ridge”, persists up to
at least vertical bar Delta eta vertical bar = 4. For particles with
transverse momenta (p(T)) of 2-4 GeV/c, the ridge is found to be most
prominent when these particles are correlated with particles of p(T) =
2-6 GeV/c, and to be much reduced when paired with particles of p(T) =
10-12 GeV/c."
