Modeling Quasi-elastic Form Factors for Electron and Neutrino Scattering
We calculate the total and di erential quasielastic cross sections for neutrino and antineutrino scattering on nucleons using up to date ts to the nucleon elastic electromagnetic form factors GpE , G n E , G p M , G n M , and weak and pseudoscalar form factors. We nd that using the updated non-zero value of GnE has a signi cant e ect on both the total and di erential neutrino and antineutrino q...
متن کاملNeutron Form Factors from Quasi-Elastic Electron-Deuteron Scattering
The differential cross section for quasi-elastic electron-deuteron scattering has been measured at the Cambridge Electron Accelerator in the four-momentum-transfer region from 7 to 115 PfC0.27 to 4.47 (Bev/~)~] . The method used involved a coincidence between scattered electrons and recoiling protons. Electrons without a high-energy proton in coincidence were assumed to be due to a neutron inte...
متن کاملForm Factors and Diffractive Scattering ?
Hadronic elastic and transition form factors are used to describe elastic nucleon-nucleon and pion-nucleon scattering, as well as diffractive excitation of nucleon resonances in an optical model. Very good quantitative agreement with available experimental results is obtained.
متن کاملGpds, Form Factors and Compton Scattering
As is well-known factorization is an important property of QCD whithout which we would not be able to calculate form factors or cross sections. Factorization into a hard parton-level subprocess to be calculated from perturbative QED and/or QCD, and soft hadronic matrix elements which are subject to non-perturbative QCD and are not calculable at present, has been shown to hold for a number of re...
متن کاملParton Distributions, Form Factors and Compton Scattering
The soft physics approach to form factors and Compton scattering at moderately large momentum transfer is reviewed. It will be argued that in that approach the Compton cross section is given by the Klein-Nishina cross section multiplied by a factor describing the structure of the proton in terms of two new form factors. These form factors as well as the ordinary electromagnetic form factors rep...
