Hadron and Photon Production in the Forward Region at RHIC and LHC

Abstract

In this paper we investigate the hadron and photon production at forward rapidities in $pp$ and $pA$ collisions considering two phenomenological models based on the Color Glass Condensate formalism. The predictions of these models for the hadron spectra are compared with the dAu and pp RHIC data and the nuclear modification factor $R_{hA}$ is estimated. Our results demonstrate that the analysis of the transverse momentum dependence of this factor allows to discriminate between the phenomenological models. Furthermore, we predict $R_{hA}$ for photon production at forward rapidities at RHIC and LHC energies and study the $p_T$ dependence of the photon to pion production ratio.
