Long range rapidity correlations and jet production in high energy nuclear collisions

Abstract

The STAR Collaboration at the Relativistic Heavy Ion Collider presents a systematic study of high-transversemomentum charged-di-hadron correlations at small azimuthal pair separation in d + Au and central Au + Au collisions at s NN = 200 GeV. Significant correlated yield for pairs with large longitudinal separation is observed in central Au + Au collisions, in contrast to d +
