Abstract in English

We consider a contribution to hadroproduction in which the meson production is mediated by three-gluon partonic state, with two gluons coming from the target and one gluon from the projectile. This mechanism involves double gluon density and thus it enters at a non-leading twist, but it is enhanced at large energies due to large double gluon density at small x. The three-gluon contribution to hadroproduction is calculated within perturbative QCD in the factorization framework, and it is found to provide a significant correction to the standard leading twist cross-section at the energies of the Tevatron or the LHC. The results are given as differential -dependent cross-sections for polarization components.

This mechanism involves double gluon density and thus it enters at a non-leading twist, but it is enhanced at large energies due to large double gluon density at small x. The three-gluon contribution to $J/ \Psi$ hadroproduction is calculated within perturbative QCD in the $k_{T}$ factorization framework, and it is found to provide a significant correction to the standard leading twist cross-section at the energies of the Tevatron or the LHC. The results are given as differential $p_{T}$ -dependent cross-sections for $J/ \Psi$ polarization components.pl
