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…
Dimension Six Corrections to the Vector Sector of AdS/QCD Model
Hovhannes R. Grigoryan
We study the effects of dimension six terms on the predictions of the holographic model for the vector meson form factors and determine the corrections to the electric radius, the…
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…
The Average Kinetic Energy of the Heavy Quark in in the Bethe-Salpeter Equation Approach
Xin-Heng Guo, Heng-Kui Wu
In the previous paper, based on the heavy quark symmetries of the QCD Lagrangian in the heavy quark limit, the Bethe-Salpeter equation for the heavy bar…
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…
