“…In the perturbative approach it reduces to production of gluons, which subsequently transform into observed secondary hadrons. The study of gluon production in the central rapidity region with transverse momenta much smaller than the longitudinal momenta of the colliding particles ("Regge kinematics") has a long history, starting from the pioneer work on the production of minijets from the BFKL pomeron [1]. Later this problem was studied in the framework of the dipole picture for the inclusive cross-section in deep-inelastic scattering (DIS) on the heavy nucleus [2], where it was shown that the inclusive cross-section was related to the so-called unintegrated gluon density in the nucleus.…”

In the framework of the QCD effective action the vertices of gluon emission in interaction of reggeons are studied in the limit of small longitudinal momenta of the emitted gluon. It is found that the vertices drastically simplify in this limit so that the gluon becomes emitted from a single reggeon coupled to the projectile and target via multireggeon vertices. Contribution from this kinematical region is studied for double and 2×2 elementary collisions inside the composite projectile and target.

Investigating the inclusive transverse spectra in high-energy pp collisions in the context of geometric scaling framework

The presence of geometric scaling within the p T spectra of produced hadrons at high energy pp collisions using small-x k T-factorization is investigated. It is proposed a phenomenological parameterization for the unintegrated gluon distribution in the scaling range that reproduces the features of the differential cross section both in the saturated and dilute perturbative QCD regimes. As the saturation scale acts as an effective regulator of the infrared region, the extension of the model to quantities usually associated to soft physics is studied. The approach is applied to compute the average p T and the rapidity distribution of produced gluons at high energies.
