Charmonium Polarization in High Energy Collisions

Autor: Saleev, V. A., Vasin, D. V.

Publikováno v: Proc.of XI Workshop on High Energy Spin Physics, Dubna, Sept. 27, 2005: p.133-138, JINR(2006)

We consider charmonium polarization at high-energy hadron collider Tevatron in the framework of the nonrelativistic QCD (NRQCD) and the k_T-factorization approach. The polarization effects are studied for the direct and the prompt production channels

Bottomonium Production in the Regge Limit of QCD

Autor: Kniehl, B. A., Saleev, V. A., Vasin, D. V.

Publikováno v: Phys.Rev.D74:014024,2006

We study bottomonium hadroproduction in proton-antiproton collisions at the Fermilab Tevatron in the framework of the quasi-multi-Regge kinematics approach and the factorization formalism of non-relativistic QCD at leading order in the strong-couplin

Charmonium Production at High Energy in the k_T-Factorization Approach

Autor: Kniehl, B. A., Vasin, D. V., Saleev, V. A.

Publikováno v: Phys.Rev.D73:074022,2006

We study charmonium production at high-energy colliders (Tevatron, HERA, and LEP2) in the framework of the k_T-factorization approach and the factorization formalism of non-relativistic quantum chromodynamics at leading order in the strong-coupling c

Production of B(c) mesons via fragmentation in the kT-factorization approach

Autor: Saleev, V. A., Vasin, D. V.

Publikováno v: Phys.Lett.B605:311-318,2005

In the framework of the kT-factorization approach we have calculated in the fragmentation model the pT-spectra of B(c) mesons at the energies of the Tevatron and the LHC Colliders and at the large pT domain. We compare the obtained results with the e

Charm content of a proton in collinear parton model and in k_T-factorization approach

Autor: Saleev, V. A., Vasin, D. V.

Publikováno v: Proc. of Int. Workshop DIS-2003, St.Peterburg, 23-27 Apr 23

It is shown that the difference between the c-quark proton structure functions calculated in the k_T-factorization approach using different unintegrated gluon distribution functions is the same order as the difference between results obtained in the

Direct J/psi and psi' hadroproduction via fragmentation in the collinear parton model and k_T-factorization approach

Autor: Saleev, V. A., Vasin, D. V.

Publikováno v: Phys.Rev.D68:114013,2003

The p_T-spectra for direct J/psi and psi' in hadroproduction at Tevatron energy have been calculated based on NRQCD formalism and fragmentation approximation in the collinear parton model and k_T-factorization approach. We have described the CDF data

On charmonia and charmed mesons photoproduction at high energy

Autor: Saleev, V. A., Vasin, D. V.

Publikováno v: Phys.Lett. B548 (2002) 161-174

We compare the predictions of the collinear parton model and the k_T-factorization approach in J\Psi and D^\star meson photoproduction at HERA energies. It is shown that obtained in the both approaches D^\star meson spectra over p_T and \eta as well
