چکیده

The pion electromagnetic form factor has been calculated for the first time from solutions of Bethe-Salpeter equation, obtained directly in Minkowski space by using Nakanishi integral representation amplitude. one-gluon exchange kernel contains as inputs quark and gluon masses, well a scale parameter featuring extended quark-gluon vertex. range variability these parameters is suggested lattice calculations. After presenting very successful comparison with existing data whole momentum transfer, we show how inserting light-front (LF) formalism our approach allows to achieve further interesting results, like evaluation LF valence investigation end-points effects.

The Electromagnetic Pion Form Factor and Instantons

We calculate the electromagnetic pion form factor at intermediate spacelike momentum transfer from the QCD sum rule for the correlation function of two pseudoscalar interpolating fields and the electromagnetic current. This correlator receives essential contributions from direct (i.e. small-scale) instantons, which we evaluate under the assumption of an instanton size distribution consistent wi...

Pion electromagnetic form factor at finite temperature.

Temperature effects on the electromagnetic couplings of pions in hot hadronic matter are studied with an effective chiral Lagrangian. We show that the Ward-Takahashi identity is satisfied at non-zero temperature in the soft pion limit. The in-medium electromagnetic form factor of the pion is obtained in the time-like region and shown to be reduced in magnitude, especially near the vector-meson ...

Electromagnetic Form Factor of the Pion

The Standard Model prediction for the magnetic moment of the muon requires a determination of the electromagnetic form factor of the pion at high precision. It is shown that the recent progress in ππ scattering allows us to obtain an accurate representation of this form factor on the basis of the data on e+e− → π+π−. The same method also applies to the form factor of the weak vector current, wh...

Electromagnetic pion form factor at finite temperature

The electromagnetic form factor of the pion in the space-like region, and at finite temperature, Fπ(Q 2, T ), is obtained from a QCD Finite Energy Sum Rule. The form factor decreases with increasing T, and vanishes at some critical temperature, where the pion radius diverges. This divergence may be interpreted as a signal for quark deconfinement. John Simon Guggenheim Fellow 1994-1995 The possi...

Electromagnetic 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...
