Gluon saturation and leading particle spectra in pp collisions

Abstract

In this work we use the IGM, a model that describes well the energy flux in hadronic collisions, to study the leading particle spectrum when saturation effects on the gluon distribution function are included. The leading particle spectrum is calculated for several center of mass energies ( √ s). In the very high energy limit we compare our results with the predictions made in a recent paper, which also addresses the same problem.
