Real Compton Scattering at High P ⊥
نویسنده
چکیده
Compton scattering (γ+p → γ+p) in the hard scattering limit is a potentially powerful probe of the short-distance structure of the nucleon. It is a natural complement to high Q exclusive reactions, such as elastic form factors and deeply virtual Compton scattering (DVCS), where the common feature is a hard energy scale, leading to a factorization of the transition amplitude into a part involving the overlap of soft (nonperturbative) wave functions and a perturbative hard scattering amplitude (HSA). For Real Compton Scattering (RCS), the hard scale is achieved when both s and the transverse momentum transfer p⊥ are large, and under these conditions RCS is sometimes referred to as “Wide-Angle Compton Scattering.” There are two types of questions that are interesting to investigate:

Introduction:In PET imaging, one or both of two annihilation photons may change the direction before reaching the detector due to Compton scattering interaction in body. .Methods:This article, a Monte Carlo simulation study, examined the effect of soft tissue on this error.In this work, the PET BiographTM 6 scanner, a simple geometry of soft tissue -including a sphere of soft tissue in center ...
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...

The soft physics approach to Compton scattering at moderately large momentum transfer is reviewed. It will be argued that in that approach the Compton cross section as well as other exclusive observables exhibit approximate scaling in a limited range of momentum transfer.

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 کاملProton Compton Scattering and Photoproduction of Vector Mesons
Proton Compton scattering and photoproduction of vector mesons at high energies are studied in terms of the quark model. It is shown that under the vector meson dominance hypothesis the quark model gives the rP total hadronic cross section in good agreement with the experimental data. The real-to-imaginary ratio of forward proton Compton scattering is related to the total cross sections and the...
