Resumo
© Published under licence by IOP Publishing Ltd.We compute the energy and rapidity dependence of the average transverse momentum 〈pT〉 in pp and pA collisions at RHIC and LHC energies in the framework of 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 the 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.
