Z_N-symmetry in gauge theories at finite temperatures
V. M. Belyaev
The role of Z_N symmetry in gauge theories at finite temperatures is discussed. This symmetry is studied in terms of A_0-effective potential. We consider two- and four-dimensional…
Deep Inelastic Scattering and Light-Cone Wave Functions
V. M. Belyaev, Mikkel B. Johnson
In the framework of light-cone QCD sum rules, we study the valence quark distribution function of a pion for moderate . The sum rule with the leading twist-2 wave fun…
Form Factors in QCD
V. M. Belyaev, A. V. Radyushkin
We use local quark-hadron duality to estimate the purely nonperturbative soft contribution to the form factors. Our results are in agreement with existing experimenta…
Delta-Isobar Magnetic Form Factor in QCD
V. M. Belyaev
We consider the QCD sum rules approach for Delta-isobar magnetic form factor in the infra-red region . The QCD sum rules in external variable field are used. The obta…
