Abstract

The energy and rapidity dependence of the average transverse momentum (pT) in pp and pA collisions at energies currently available at the BNL Relativistic Heavy Ion Collider (RHIC) and CERN Large Hadron Collider (LHC) are estimated using the color glass condensate (CGC) formalism. We update previous predictions for the pT spectra using the hybrid formalism of the CGC approach and two phenomenological models for the dipole-target scattering amplitude. We demonstrate that these models are able to describe the RHIC and LHC data for hadron production in pp, dAu, and pPb collisions at pT≤20 GeV. Moreover, we present our predictions for (pT) and demonstrate that the ratio (pT(y))/(pT(y=0)) decreases with the rapidity and has a behavior... (More)

We demonstrate that these models are able to describe the RHIC and LHC data for hadron production in pp, dAu, and pPb collisions at pT≤20 GeV. Moreover, we present our predictions for (pT) and demonstrate that the ratio (pT(y))/(pT(y=0)) decreases with the rapidity and has a behavior similar to that predicted by hydrodynamical calculations.
