Nucleon Compton Scattering with Two Space–like Photons
نویسنده
چکیده
We calculated two–photon exchange effects for elastic electron–proton scattering at high momentum transfers. The corresponding nucleon Compton amplitude is defined by two space–like virtual photons that appear to have significant virtualities. We make predictions for a) a single–spin beam asymmetry, and b) a single–spin target asymmetry or recoil proton polarization caused by an unpolarized electron beam.

Proton-antiproton Annihilation into Two Photons at Large S
Exclusive proton–antiproton annihilation into two photons can be viewed as the Compton process in the crossed channel. At large s (≈ 10 GeV 2) and |t|, |u| ∼ s this process can be described by a generalized partonic picture, analogous to the " soft mechanism " in wide–angle real Compton scattering. The two photons are emitted in the annihilation of a single fast quark and antiquark (" handbag g...

At the beginning of thermonuclear ignition in fusion plasma, the bremsstrahlung radiation is dominant phenomenon, the photons distribution function is Planckian and plasma is considered as optically thick one. But at a certain energy, the bremsstrahlung radiation and Compton scattering losses rates become equal and plasma makes a transition from optically thick to optically thin and photons dis...

Static nucleon polarisabilities gauge the stiffness of the nucleon against an external electro-magnetic field, parameterising the part of the real Compton amplitude at zero energy which is not explained by the pole terms, i.e. by the successive interactions of two photons with a point-like nucleon of anomalous magnetic moment κ. Dynamical nucleon polarisabilities are the energy dependent genera...

متن کاملSingle spin asymmetries in elastic electron-nucleon scattering
We discuss the target and beam normal spin asymmetries in elastic electron-nucleon scattering which depend on the imaginary part of two-photon exchange processes between electron and nucleon. In particular, we estimate these transverse spin asymmetries for beam energies below 2 GeV, where the twophoton exchange process is dominated from the resonance contribution to the doubly virtual Compton s...
