Forward azimuthal correlations in 200 GeV p+p and d+Au collisions at STAR
Abstract
Forward particle production and correlation measurements at RHIC can probe low- gluons. The suppression observed in back-to-back forward +forward 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- is in a dense gluon state. The forward + near-forward jet-like cluster azimuthal correlations in 200 GeV p+p and d+Au collisions at STAR are studied, which are sensitive to the intermediate x region between forward+mid-rapidity correlations and forward+forward correlations. Together with the other measurements from STAR, which probe different regions of x, forward+near-forward di-hadron correlations can provide information to understand how sharp is the transition from dilute parton gas to dense gluon state.
