| contents | Within the framework of numerical simulations, this work investigates the influence of the QCD analogue of the inverse Compton effect (ICE) in the quark--gluon scattering process qg \rightarrow qg on the transverse momentum p_T and pseudorapidity eta distributions of secondary particles produced in proton--proton collisions at energies sqrt{s}=30 GeV, 510 GeV, 14 TeV. In the present context, ICE refers to a class of parton-level kinematic configurations in which the incoming quark carries a larger fraction of energy than the gluon, in contrast to the complementary DCE regime. The simulations were performed using the PYTHIA~8.316 event generator. It is shown that the relative contributions of ICE and DCE strongly depend on the collision energy. As the energy increases from sqrt{s}=30 GeV to sqrt{s}=14 TeV, the ICE contribution becomes comparable to or exceeds the DCE contribution over a broad p_T range. The analysis of pseudorapidity distributions demonstrates that deviations of the ICE/DCE ratio from unity appear predominantly in the central region |eta| simeq 0, corresponding to symmetric partonic configurations x_1 sim x_2, whereas in peripheral regions the ratio approaches unity. The obtained results indicate that, with increasing collision energy, the contribution of ICE-like processes grows due to the enhanced role of gluon collisions in the small-x region. |
