Anomalous Form Factor of the Neutral Pion in Extended AdS/QCD Model with Chern-Simons Term
H. R. Grigoryan, A. V. Radyushkin
We propose an extension of the hard-wall AdS/QCD model by including the Chern-Simons term required to reproduce the chiral anomaly of QCD. In the framework of this holographic mode…
Pion Form Factor in Chiral Limit of Hard-Wall AdS/QCD Model
H. R. Grigoryan, A. V. Radyushkin
We develop a formalism to calculate form factor and charge density distribution of pion in the chiral limit using the holographic dual model of QCD with hard-wall cutoff. We introd…
Structure of Vector Mesons in Holographic Model with Linear Confinement
H. R. Grigoryan, A. V. Radyushkin
Wave functions and form factors of vector mesons are investigated in the holographic dual model of QCD with a smooth oscillator-like wall. We introduce wave functions conjugate to…
Form Factors and Wave Functions of Vector Mesons in Holographic QCD
Hovhannes R. Grigoryan, Anatoly V. Radyushkin
Within the framework of a holographic dual model of QCD, we develop a formalism for calculating form factors of vector mesons. We show that the holographic bound states can be desc…
Weak Deeply Virtual Compton Scattering
A. Psaker, W. Melnitchouk, A. V. Radyushkin
We extend the analysis of the deeply virtual Compton scattering process to the weak interaction sector in the generalized Bjorken limit. The virtual Compton scattering amplitudes f…
Deep Elastic Processes of Composite Particles in Field Theory and Asymptotic Freedom
A. V. Radyushkin
This is an English translation of my 1977 Russian preprint. It contains the first explicit definition of the pion distribution amplitude (DA), the expression for the pion form fact…
