Regge Behavior of DIS Structure Functions
Franz Gross, I. V. Musatov, Yu. A. Simonov
Building on previous works of the mid 1960's, we construct an integral equation for forward elastic scattering (t=0) at arbitrary virtuality Q^2 and large s=W^2. This equation sums…
Power-Law Wave Functions and Generalized Parton Distributions for Pion
A. Mukherjee, I. V. Musatov, H. C. Pauli +1
We propose a model for generalized parton distributions of the pion based on the power-law ansatz for the effective light-cone wave function.
Evolution and models for skewed parton distributions
I. V. Musatov, A. V. Radyushkin
We discuss the structure of the ``forward visible'' (FW) parts of double and skewed distributions related to usual distributions through reduction relations. We use factorized mode…
The elastic contribution to the Burkhardt -- Cottingham and Generalized Gerasimov--Drell-Hearn Sum Rules
I. V. Musatov, O. V. Teryaev, A. Schäfer
The elastic contribution to the first moment of is analysed using a Drell-Yan-West type of relation and is shown to be negative. For a qualitative estimate the one-loo…
Transverse Momentum and Sudakov Effects in Exclusive QCD Processes: gamma* gamma pi0 Form Factor
I. V. Musatov, A. V. Radyushkin
We analyze effects due to transverse degrees of freedom in QCD calculations of the fundamental hard exclusive amplitude of transition. A detailed discussion is given…
Additional Degrees of Freedom in Skyrmion Motion
I. V. Musatov, V. A. Nikolaev, E. Sorace +2
We consider the quantization of chiral solitons with baryon number . Classical solitons are obtained within the framework of a variational approach. From the form of the solit…
