Nucleon form factors '99

  title={Nucleon form factors '99},
  author={K. Jager and B. Pire},
  journal={Nuclear Physics},
The authors review recent progress in the experimental knowledge of and theoretical speculations about nucleon form factors, with special emphasis on the large Q{sup 2} region. There is now a long history of continuous progress in the understanding of electromagnetic form factors at large momentum transfer. After the pioneering works leading to the celebrated quark counting rules, the understanding of hard scattering exclusive processes has been solidly founded. A perturbative QCD subprocess is… Expand

QCD analysis of p¯N→γ∗π in the scaling limit
Abstract We study the scaling regime of nucleon–antinucleon annihilation into a deeply virtual photon and a meson, p ¯ N → γ ∗ π , in the forward kinematics, where | t | ≪ Q 2 ∼ s . We obtain theExpand


Nonforward parton densities and soft mechanism for form factors and wide-angle Compton scattering in QCD
The authors argue that at moderately large momentum transfer {minus}t {approx_lt} 10 GeV{sup 2}, hadronic form factors and wide-angle Compton scattering amplitudes are dominated by mechanismExpand
Asymptotic Behavior of Composite Particle Form-Factors and the Renormalization Group
Composite-particle form factors are studied in the limit of large momentum transfer Q. It is shown that in models with spinor constituents and either scalar or gauge vector gluons, the mesonExpand
The perturbative proton form factor reexamined
Abstract. We recalculate the proton Dirac form factor based on the perturbative QCD factorization theorem, which includes Sudakov suppression. The evolution scale of the proton wave functions and theExpand
The application of simple dimensional counting to bound states of pointlike particles enables us to derive scaling laws for the asymptotic energy dependence of electromagnetic and hadronic scatteringExpand

The difference between the timelike and spacelike meson form factors is analyzed in the framework of perturbative QCD with Sudakov effects included. It is found that integrable singularities appearExpand
Hadronic form factors: Perturbative QCD vs. QCD SUM rules
The challenging problem of applicability of the perturbative QCD to exclusive processes is revealed.The basic ingredients both of the asymptotic large Q2 analysis and of the QCD sum rule approach areExpand
On exclusive reactions in the time-like region
Abstract The electromagnetic form factors of the proton in the time-like region and two-photon annihilations into proton-antiproton are investigated. To calculate these processes at moderately largeExpand
The applicability of perturbative QCD to exclusive processes
Abstract We re-examine our arguments against the dominance of perturbative QCD over soft, non-perturbative effects in exclusive processes at currently available Q 2 . We continue to find thatExpand
Polarization transfer in elastic electron scattering from nucleons and deuterons
We present a description, including relevant formulas and numerical estimates, of a set of polarization transfer experiments which appear to offer a feasible way to separate the deuteron charge andExpand
The charge form factor of the neutron from the reaction \pol(2h)(\pol(e), e’n)p
We report on the first measurement of spin-correlation parameters in quasifree electron scattering from vector-polarized deuterium. Polarized electrons were injected into an electron storage ring atExpand
