“…There are two quite different approaches to calculate nucleon form factors. In the first kind, the mesonic degrees of freedom are explicit, as in calculations based on Vector Meson Dominance (VMD) [19][20][21][22], models comprising a threequark core dressed with pseudoscalar mesons [23], and a calculation based on the solitonic nature of the nucleon [24]. The second kind are QCD-based quark models; these include models such as relativistic constituent quark (RCQM) [25][26][27], diquark [28], cloudy bag [29], and QCD sum rule [30].…”

“…Linear combinations of the six charge-normalized yields Y hm define all five polarization observables in Eq. (2). The experimental value of the beam-vector polarization observable A V ed can be written as…”

Electroweak structure of the nucleon, meson cloud, and light-cone wave functions

“…The problem of considering the meson cloud surrounding a system of three valence quarks has been addressed already in the past in a variety of papers (see, e.g., [34,35,36,37,38,39,40,41,42] and references therein). Along the lines originally proposed in Refs.…”
