Gluon saturation and inclusive production at low transverse momenta

Abstract

In this letter we suggest the generalization of $k_T$-factorization formula for inclusive gluon production for the dense-dense parton system scattering. It turnes out that the soft gluon production with transverse momentum $p_T$ is suppressed by additional Sudakov-like factor that depends on $p_T^2/Q_s^2$ ratio in a good agreement with the first numerical calculation in Colour Glass Condensate approach by J.P. Blaizot, T. Lappi and Y. Mehtar-Tan.
