Polarizability of the Nucleon and Compton Scattering
One of the central challenges of hadron physics in the regime of strong (non-perturbative) QCD is to identify the relevant degrees of freedom of the nucleon and to quantitatively explain experimental data in terms of these degrees of freedom. Among the processes studied so far Compton scattering plays a prominent role because of the well understood properties of the electromagnetic interaction....
متن کاملLow Energy Compton Scattering and Nucleon Structure
The low energy virtual Compton scattering process eN → eNγ offers a new and potentially high resolution window on nucleon structure via measurement of so-called generalized polarizabilities (GPs). We present calculations of GPs within heavy baryon chiral perturbation theory and discuss present experimental efforts.
متن کاملTJNAF E93-050 Nucleon Structure Study by Virtual Compton Scattering
Virtual Compton Scattering (VCS), which can be studied in the reaction e+p! e0+p+ , is a powerful new tool to access nucleon structure. It is the natural complement to form factor measurements, real Compton scattering ( + p ! 0 + p), and realand virtualphotoproduction. The p(e; e0p) reaction includes the coherent sum of the VCS amplitude and the Bethe-Heitler (BH) or radiative tail amplitude. I...
متن کاملNucleon Polarisabilities from Compton Scattering on the Deuteron
An analytic calculation of the differential cross section for elastic Compton scattering on the deuteron at photon energies ω in the range of 25 − 50 MeV is presented to next-to-next-to-leading order, i.e. to an accuracy of ∼ 3%. The calculation is model-independent and performed in the low energy nuclear Effective Field Theory without dynamical pions. The iso-scalar, scalar electric and magnet...
متن کاملReal and Virtual Compton Scattering off the Nucleon
A review is given of the very recent developments in the fields of real and virtual Compton scattering off the nucleon. Both real and virtual Compton scattering reactions are discussed at low outgoing photon energy where one accesses polarizabilities of the nucleon. The real Compton scattering at large momentum transfer is discussed which is asymptotically a tool to obtain information on the va...
