Studies on the electromagnetic structure of the nucleon by free and quasi-free Compton scattering at MAMI (Mainz)
نویسنده
چکیده
Using hydrogen and deuterium targets, Compton scattering by the proton and neutron have been studied at the tagged photon beam of the MAMI (Mainz) accelerator using different experimental setups. The theoretical tools for the analysis of the experimental data have been investigated, as there are the nonsubtracted dispersion theory and the theory of quasi-free reactions on the proton and neutron bound in the deuteron. Experimental Compton scattering data are understood in the first and second resonance region with good precision. Precise electromagnetic polarizabilities and spin polarizabilities for the proton and the neutron have been determined.

Spin polarizabilities and polarizabilities of the nucleon studied by free and quasi-free Compton scattering at MAMI (Mainz)
In addition to the E2/M1 ratio of the N → ∆ transition, the electromagnetic polarizabilities and spin-polarizabilities are important structure constants of the nucleon which serve as sensitive tests of chiral perturbation theory and of models of the nucleon. Recently, these quantities have been investigated experimentally at MAMI (Mainz) by high-precision Compton scattering using hydrogen and d...
متن کاملMeasurement of the beam-helicity asymmetry I in the photoproduction of π0π± pairs off protons and off neutrons
Beam-helicity asymmetries have been measured at the MAMI accelerator in Mainz for the photoproduction of mixed-charge pion pairs in the reactions γp → nππ off free protons and γd → (p)pπ0π− and γd → (n)nππ off quasi-free nucleons bound in the deuteron for incident photon energies up to 1.4GeV. Circularly polarized photons were produced from bremsstrahlung of longitudinally polarized electrons a...

In this paper, we calculate nuclear structure function and EMC effect of 40Ca and 56Fe nuclei. To achive the goals, we consider Fermi motion and binding energy contrbiution in the harmonic oscillator model. In this model, harmonic oscillator parameter ħω related to shells root mean square radius and for free nucleon structure functions, is obtained from GRV’s free nucleon structure functions. ...
متن کاملDispersion Analysis for Generalized Spin Polarizabilities
Over the past years, the virtual Compton scattering (VCS) process on the proton, accessed through the ep → epγ reaction, has become a powerful tool to provide new information on the internal structure of the nucleon . In the low energy regime below pion threshold, the outgoing photon in the VCS process plays the role of a quasi-constant applied electromagnetic dipole field and, through electron...
متن کاملChiral perturbation theory Success and challenge
Chiral perturbation theory is the efiective fleld theory of the strong interactions at low energies. We will give a short introduction to chiral perturbation theory for mesons and will discuss, as an example, the electromagnetic polarizabilities of the pion. These have recently been extracted from an experiment on radiative π photoproduction from the proton (γp → γπn) at the Mainz Microtron MAM...
