The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; show every role.

RHIC experiments have recently measured the azimuthal correlation function of forward di-hadrons. The data show a disappearance of the away-side peak in central d+Au collisions, compared to p+p collisions, as was predicted by saturation physics. Indeed, we argue that this effect, absent at mid-rapidity, is a consequence of the small-x evolution into the saturation regime of the Gold nucleus wave function. We show that the data are well described in the Color Glass Condensate framework.

We observe depletion of the back-to-back correlations in central $dAu$ collisions in the forward direction consistent with the Color Glass Condensate predictions.

Unveiling the nuclear structure at small x using azimuthal correlations in dA collisions · 0.96
It is demonstrated that the suppression and broadening of the away side peak provide a unique signal for the onset of the saturation mechanism at small-$x$ in a large nucleus.

Back-to-Back Correlations of Di-hadrons in dAu Collisions at RHIC · 0.90
The suppression observed in back-to-back forward $\pi^{0}$+forward $\pi^{0}$ correlations at STAR in central d+Au collisions at STAR is consistent with a prediction of the Color Glass Condensate (CGC) calculation, indicating the gold nucleus probed at such low-$x$ is in a dense gluon state.

Forward azimuthal correlations in 200 GeV p+p and d+Au collisions at STAR · 0.90
A suppression of the back-to-back azimuthal correlations was observed in d+Au, qualitatively consistent with the gluon saturation picture.

Our analysis provides further evidence for the presence of saturation effects in RHIC data.

Azimuthal correlations of forward di-hadrons in d+Au collisions at RHIC in the Color Glass Condensate · 0.84
We calculate azimuthal correlations in dAu collisions at different rapidities and centralities and argue that experimentally observed depletion of the back-to-back pick can be quantitatively explained by gluon saturation in the Color Glass Condensate of the Gold nucleus.
