Pion Form Factor in Large N C Qcd *
The electromagnetic form factor of the pion is obtained using a particular realization of QCD in the large Nc limit, which sums up the infinite number of zero-width resonances to yield an Euler’s Beta function of the Veneziano type. This form factor agrees with space-like data much better than single rho-meson dominance. A simple unitarization ansatz is illustrated, and the resulting vector spe...
متن کاملPion Form Factor in QCD at Intermediate Momentum Transfers
We present a quantitative analysis of the electromagnetic pion form factor in the light-cone sum rule approach, including radiative corrections and higher-twist effects. The comparison to the existing data favors the asymptotic profile of the pion distribution amplitude and allows to estimate the deviation: ( ∫ du/uφπ(u))/( ∫ du/uφas π (u)) = 1.1± 0.1 at the scale 1 GeV. Special attention is pa...
متن کاملPion structure from improved lattice QCD: form factor and charge radius at low masses
The charge form factor of the pion is calculated in lattice QCD. The non-perturbatively improved Sheikholeslami-Wohlert action is used together with the O(a) improved vector current. Other choices for the current are examined. The form factor is extracted for pion masses from 970 MeV down to 360 MeV and for momentum transfers Q2 ≤ 2 GeV. The mean square charge radius is extracted, compared to p...
متن کاملPion form factor from local-duality QCD sum rule
We present our recent results for the pion elastic form factor [1] obtained within a local-duality three-point sum rule (a Borel sum rule in the limit of an infinite Borel parameter). Our analysis [1] includes the O(1) and O(αs) contributions and is therefore applicable in a broad range of spacelike momentum transfers. Our results demonstrate in essentially model-independent way that the O(1) t...
متن کاملTwisted mass QCD for the pion electromagnetic form factor
The pion form factor is computed using quenched twisted mass QCD and the GMRES-DR matrix inverter. The momentum averaging procedure of Frezzotti and Rossi is used to remove leading lattice spacing artifacts, and numerical results for the form factor show the expected improvement with respect to the standard Wilson action. Although some matrix inverters are known to fail when applied to twisted ...
