Pion Loop Contribution to the Electromagnetic Pion Charge Radius
A phenomenological Dyson-Schwinger equation approach to QCD, formalised in terms of a QCD based model field theory, is used to calculate the electromagnetic charge radius of the pion. The contributions from the quark core and pion loop, as defined in this approach, are identified and compared. It is shown explicitly that the divergence of the charge radius in the chiral limit is due to the pion...
متن کاملPion charge radius from charged pion electroproduction
We analyze a low-energy theorem of threshold pion electroproduction which allows one to determine the charge radius of the pion. We show that at the same order where the radius appears, pion loops induce a correction to the momentum dependence of the longitudinal dipole amplitude L01 (2) . This model-independent correction amounts to an increase of the pion charge radius squared from the electr...
متن کاملThe Quark-Photon Vertex and the Pion Charge Radius
The rainbow truncation of the quark Dyson–Schwinger equation is combined with the ladder Bethe–Salpeter equation for the dressed quark-photon vertex to study the low-momentum behavior of the pion electromagnetic form factor. With model gluon parameters previously fixed by the pion mass and decay constant, the pion charge radius rπ is found to be in excellent agreement with the data. When the of...
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...
متن کاملThe scalar radius of the pion
The pion scalar radius is given by 〈r S〉 = (6/π) ∫ ∞ 4M2 π ds δS(s)/s , with δS the phase of the scalar form factor. Below K̄K threshold, δS = δπ , δπ being the isoscalar, S-wave ππ phase shift. At high energy, s > 2GeV , δS is given by perturbative QCD. In between I argued, in a previous letter, that one can interpolate δS ∼ δπ, because inelasticity is small, compared with the errors. This give...
