Qcd Sum Rules and Compton Scattering
We extend QCD sum rule analysis to moderate energy fixed angle Compton scattering. In this kinematic region there is a strong similarity to the sum rule treatment of electromagnetic form factors, although the four-point amplitude requires a modification of the Borel transform. To illustrate our method, we derive the sum rules for helicity amplitudes in pion Compton scattering and estimate their...

متن کاملLow-energy Compton scattering on the nucleon and sum rules
The Gerasimov-Drell-Hearn and Baldin-Lapidus sum rules are evaluated in a relativistic, unitary, crossing symmetric and gauge-invariant model for photon-induced reactions on the nucleon. The property of analyticity is partially incorporated through a dressing procedure for propagators and vertices. The sum α + β of the electric and magnetic polarisabilities and the forward spin polarisability γ...
متن کاملCompton scattering as a probe for materials investigation
This article investigates into the feasibility of using gamma radiation Compton backscatter spectra as a means of material characterization, with the view to developing a portable, hand held probe for investigative purposes such as searching for illicit substances hidden in wall or car door cavities.
متن کاملA New Kinetic Equation for Compton Scattering
A kinetic equation for Compton scattering is given that differs from the Kompaneets equation in several significant ways. By using an inverse differential operator this equation allows treatment of problems for which the radiation field varies rapidly on the scale of the width of the Compton kernel. This inverse operator method describes, among other effects, the thermal Doppler broadening of s...
