Heavy Quark Pair Production in Polarized Photon--Photon Collisions
George Jikia, Avto Tkabladze
We present the next-to-leading-order cross sections of the heavy quark-antiquark pair production in polarized photon-photon collision for the general case of photon polarizations.…
On the Gauge Invariance of the Z-Boson Mass
J. Gegelia, G. Japaridze, A. Tkabladze +2
The different schemes for the definition of the Z boson mass are analyzed. It is shown that the scheme, defining the mass as pole of the real part of the Z boson propagator and the…
Color Octet Contribution to J/psi Photoproduction Asymmetries
George Japaridze, Wolf-Dieter Nowak, Avto Tkabladze
We investigate photoproduction asymmetries in the framework of the NRQCD factorization approach. It is shown that the color octet contribution leads to large uncertainties in…

Nucleon Mass Corrections to Spin Dependent Structure Functions and Relations Between their Twist-3 Contributions
J. Blumlein, A. Tkabladze
The nucleon mass corrections are calculated to all polarized structure functions for neutral and charged current deep inelastic scattering in lowest order in the coupling constant.…
Target Mass Corrections to the Spin-dependent Structure Functions
J. Blümlein, A. Tkabladze
The target mass corrections to the twist-2 contributions of the spin-dependent structure functions are calculated using operator product expansion in lowest order in QCD. The influ…
