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 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...
متن کاملElectromagnetic Pion Form Factor and Neutral Pion Decay Width
The electromagnetic pion form factor, Fπ(q 2), is calculated for spacelike-q2 in impulse approximation using a confining quark propagator, S, and a dressed quarkphoton vertex, Γμ, obtained from realistic, nonperturbative Dyson-Schwinger equation studies. Good agreement with the available data is obtained for Fπ(q 2) and other pion observables, including the decay π0 → γ γ. This calculation sugg...
