  We compute dihadron correlations in forward deuteron-gold or proton-gold
collisions. The running coupling BK equation is used to calculate the energy
dependence of the dipole cross sections and extended to higher point Wilson
line correlators using a factorized Gaussian approximation. Unlike some earlier
works we include both the "inelastic" and "elastic" contributions to the
dihadron cross section. We show that the double parton scattering contribution
is included in our calculation and obtain both an away side peak that roughly
agrees with experimental observations and an estimate for the azimuthal
angle-independent pedestal. We find that nonlinear effects for momenta close to
the saturation scale are clearly visible in the away side peak structure.
