Type: Parallel Session: QCD and hadron structure-B6
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%.
