We extend the color glass condensate (CGC) approach to a calculation of the double inclusive gluon production by including the high density effect in the CGC wave function of the projectile (proton). Our main result is that these effects lead to the appearance of odd harmonics in the two particle correlation C(k,p). We find that in the high momentum limit, |k|,|p|Qs, this results in a positive c1{2}. Additionally when the magnitudes of the two momenta are approximately equal, |k|/|p|≈1, the density effects also generate a positive third harmonic c3{2}, which translates into a nonvanishing v3 when the momenta of the trigger and an associated particle are in the same momentum bin. The sign of c3{2} becomes negative when |k|/|p|>1.1 suggesting an interesting experimental signature.
