We investigate the azimuthal correlations of the glasma in p-p collisions at √ sNN = 7 TeV by using the CGC formalism. As expected, the azimuthal correlations show two peaks at ∆φ = 0 and π which represent collimation production in CGC. Beyond that, azimuthal correlations show fine structures, i.e. bumps or shoulders between the two peaks, when at least one gluon has small x.The structures are demonstrated to be associated with saturation momentum, and likely appear at transverse momentum around 2Qsp = 1.8 GeV/c.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
