Parity Violation in γ−→p Compton Scattering
نویسندگان
چکیده
A measurement of parity-violating spin-dependent γ−→p Compton scattering will provide a theoretically clean determination of the parity-violating pionnucleon coupling constant h (1) πNN . We calculate the leading parity-violating amplitude arising from one-loop pion graphs in chiral perturbation theory. An asymmetry of ∼ 5×10−8 is estimated for Compton scattering of 100 MeV photons.

Parity Violation in − → γ p Compton Scattering
Polarized beam −→γ p Compton scattering provides a theoretically clean way to extract the isovector parity violating pion-nucleon coupling constant h (1) πNN . This channel is more tractable experimentally than the recently proposed extraction of h (1) πNN from the Bedaque-Savage process — polarized target γ −→p compton scattering. The leading parity violating effect is calculated using Heavy B...

The measurement of the polarization of cosmic microwave background (CMB) provides considerable useful information about different physical phenomena at the last scattering surface. The polarization of CMB is due to Compton scattering. In this work, we consider the parity violation of Compton scattering. Then we insert the new amplitude into the quantum Boltzmann equation and show that the forwa...
متن کاملParity Violation in Neutron Capture Reactions
In the last decade, the scattering of polarized neutrons on compound nucleus resonances proved to be a powerful experimental technique for probing nuclear parity violation. Longitudinal analyzing powers in neutron transmission measurements on p-wave resonances in nuclei such as La and Th were found to be as large as 10%. Here we examine the possibilities of carrying out a parallel program to me...
متن کاملNew Measurement of Parity Violation in Elastic Electron-Proton Scattering and Implications for Strange Form Factors
We have measured the parity-violating electroweak asymmetry in the elastic scattering of polarized electrons from the proton. The result is A = −15.05±0.98(stat)± 0.56(syst) ppm at the kinematic point 〈θlab〉 = 12.3 and 〈Q2〉 = 0.477 (GeV/c). The value for the strange form factor (GE +0.392G s M )/(G p M/μp) = 0.069± 0.056± 0.039 is extracted from the data, where the first error is experimental a...
متن کاملReal Compton Scattering at High P ⊥
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 involvin...
