• Nucleon and pion electromagnetic form factors in a light-front constituent quark model

  سند علمی۱۹۹۵F. Cardarelli

  Nucleon and pion electromagnetic form factors are evaluated in the spacelike region within a light-front constituent quark model, where eigenfunctions of a mass operator, reproducing a large set of hadron energy levels, are adopted and quark form factors are considered in the one

• Off–shell pion electromagnetic form factor from a gauge–invariant Nambu–Jona-Lasinio model

  سند علمی۱۹۹۴C. Weiss

  The off–shell electromagnetic vertex function of pions and kaons is studied in a bosonized Nambu–Jona-Lasinio model with a gauge–invariant proper–time cutoff. The slope of the pion form factor with respect to the pion 4–momentum is equal to the on–shell pion charge radius in the

• Pion Electromagnetic Form Factor in Virtuality Distribution Formalism

  سند علمی۲۰۱۵A. V. Radyushkin

  We discuss two applications of the Virtuality Distribution Amplitudes (VDA) formalism developed in our recent papers. We start with an overview of the main properties of the pion distribution amplitude emphasizing the quantitative measures of its width, and possibility to access

• Pion Electromagnetic Form Factor in the KT Factorization Formulae

  سند علمی۲۰۰۵Xing-Gang Wu, Tao Huang

  Based on the light-cone (LC) framework and the kT factorization formalism, the transverse momentum effects and the different helicity components’ contributions to the pion form factor Fπ(Q) are recalculated. In particular, the contribution to the pion form factor from the higher
