Probing the parton content of the nucleon
TL;DR: In this article, the parton content of the nucleon is explored within a meson-cloud model developed to derive light-cone wave functions for the physical nucleon, and the model is applied to study electromagnetic form factors, distribution amplitudes and nucleon-to-meson transition distribution amplitude.

TL;DR: In this article, the L3 detector at LEP was used to study the gamma gamma-anti-proton antiproton differential cross-section in the range of the two-photon center-of-mass energy from 2.1 GeV to 4.5 GeV.
Perturbative QCD and Electromagnetic Form Factors
Carl E. Carlson,Franz Gross +1 more
TL;DR: It is shown that the soft contribution corresponding to the particular distribution amplitudes the authors use need not be bigger than the data, and that the magnitude and sign of both nucleon magnetic form factors can be explained within perturbative QCD.
Nucleon wave functions from lattice-gauge theories: Measurements of baryonic operators
TL;DR: In this paper, measurements of the matrix elements of certain 3-quark operators that govern the short distance and light-cone properties of the proton wave function obtained on an 8 3 × 16 lattice at β = 5.7 with Wilson fermions were presented.
Leading-order perturbative QCD calculation of nucleon Dirac form factors.
TL;DR: It is shown that it is possible to fit the data for ${F}_{1}^{p}$ in the range 10-30 (GeV/c) by evaluating the strong coupling constant ${\ensuremath{\alpha}}_{s}$ (${Q}^{2}$) at the exact gluon kinematics for each diagram of the process within the integrals over the momentum fraction which govern the perturbative QCD prediction.

QCD and resonance physics. theoretical foundations
TL;DR: In this paper, a systematic study is made of the non-perturbative effects in quantum chromodynamics, where the basic object is the two-point functions of various currents and the terms of this series are shown to be of two distinct types.

QCD and Resonance Physics: Applications
TL;DR: In this article, the dispersion charmonium theory was extended to include power terms due to the nonperturbative effects of QCD, and an estimate for the gluonic vacuum expectation value was derived.

Calculation of baryon masses in quantum chromodynamics
TL;DR: In this paper, the polarization operator of quark currents with baryon quantum numbers is considered in quantum chromodynamics and the non-zero mean vacuum values of the field operator products are taken into account.
