Wave functions and form factors of vector mesons are investigated in the holographic dual model of quantum chromodynamics with oscillator-like infrared cutoff. We introduce wave functions conjugate to solutions of the 5D equation of motion and develop a formalism based on these wave functions, which are very similar to those of a quantum-mechanical oscillator. For the lowest bound state ($\ensuremath{\rho}$-meson), we show that, in this model, the basic elastic form factor exhibits the perfect…

Pion form factor in improved holographic QCD backgrounds

We extend a recent numerical calculation of the pion electromagnetic form factor ${F}_{\ensuremath{\pi}}({Q}^{2})$ in holographic QCD to study two important issues regarding the behavior of fields in

Anomalous Form Factor of the Neutral Pion in Extended AdS/QCD Model with Chern-Simons Term

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 model, we study the

We study the anomalous electromagnetic pion form factor $F_{\pi^0\gamma^*\gamma^*}$ with a set of holographic models. By comparing with the measured value of the linear slope, some of these models

We consider an interaction of a spin-3/2 field with the electromagnetic field in the framework of the hard-wall model of AdS/QCD. We write Lagrangian for this interaction including all kinds
