چکیده
We consider a bottom-up AdS/QCD model with conformal exponential deformation ekIz2 on Lorentz invariant AdS background, where kI stands for the scale k? that fixes confinement in pion case and k? kinematical energy associated virtual photon. In this we assume dimension operator creates pions at boundary as ?=3, original proposals. Regarding geometric slope related to photon field k?, analyze two cases: constant depending transferred momentum q. these cases computed electromagnetic form factor well radius. compare our results experimental data other theoretical (holographic non-holographic) models. particular, dependent scale, find good agreement available non-holographic

The pion form factor from first principles
We calculate the electromagnetic form factor of the pion in quenched lattice QCD. The non-perturbatively improved Sheikoleslami-Wohlert lattice action is used together with the O(a) improved current. We calculate form factor for pion masses down to mπ = 360 MeV . We compare the mean square radius for the pion extracted from our form factors to the value obtained from the ’Bethe Salpeter amplitu...
متن کاملThe Pion Form Factor
The pion, and specifically its charge form factor, is of key interest in the study of the quark-gluon structure of hadrons. This is exemplified by the many calculations that treat the pion as one of their prime examples. One of the reasons is that the valence structure of the pion, being 〈qq̄〉, is relatively simple. Hence it is expected that the value of the four-momentum transfer squared Q, dow...
متن کاملPerturbative Pion Form Factor Reexamined
We recalculate the pion electromagnetic form factor based on the pertur-bative QCD formalism that includes the Sudakov resummation. We take into account the evolution of the pion wave function in b, which represents the transverse extent of the pion. An infrared enhancement is observed when 1/b approaches Λ QCD. We propose to freeze the evolution of the wave function at some scale above Λ QCD ,...
متن کاملConfinement, Glueballs and Strings from Deformed AdS
e-mail: [email protected], [email protected], [email protected], [email protected] We study aspects of confinement in two deformed versions of the AdS/CFT correspondence the GPPZ dual of N = 1 Yang Mills, and the Yang Mills N = 0 dual. Both geometries describe discrete glueball spectra which we calculate numerically. The results agree at the 10% level with previo...
متن کاملQuark structure of the pion and pion form factor.
We consider the pion structure in the region of low and moderately high momentum transfers: at low Q 2 , the pion is treated as a composite system of constituent quarks; at moderately high momentum transfers, Q 2 = 10 ÷ 25 GeV 2 , the pion form factor is calculated within perturbative QCD taking into account one–gluon hard exchange. Using the data on pion form factor at Q 2 < 3 GeV 2 and pion a...
