Being motivated by the challenging problem of confinement, we investigate QCD vacuum by the center vortex model. Inspired by DMCG and IMCG methods to identify vortices in lattice calculations and using Suganuma decomposition, we show in both methods under singular center gauge fixing, vortices appear in QCD vacuum in the continuum theory. Then, using the center projection, QCD theory is reduced to ... More

This work discusses the electromagnetic (EM) pion form factor ($\pi$FF) in a deformed AdS geometry. We consider the conformal dimension of the hadron bulk field defined by the scaling dimension of the $q\,\bar{q}$ operator instead of the twist. We also compute the pion EM radius and compare it with the experimental data, finding a relative error of 30%.

We will discuss confinement in a holographic perspective. We consider one isolated quark propagating in the vacuum of the gauge theory, the dual picture is an open string attached at the conformal boundary and extending in the holographic direction. We show that there will be a drag force breaking the quark only if the dual gauge theory is confining.

In this talk, we discuss an extension to the matching procedure proposed by Brodsky and de Teramond to obtain the two-body wave functions in the light-front formalism for holographic models. We compute the light-front wave function by considering different static dilaton fields and anti–de sitter (AdS)- like geometric deformations.

We show the 't Hooft Equation and the light-front holographic Schrodinger Equation are complementary to each other in governing the longitudinal and transverse dynamics of color confinement in mesons (quark-antiquark) and baryons (quark-diquark). Together, they predict remarkably well the light, heavy-light and heavy hadrons spectroscopic data. The universal emerging hadronic scale of light-front ... More
