A bstract We introduce a novel bootstrap method for heavy-mass effective field theory classical Compton scattering amplitudes involving two massless particles and arbitrary-spin infinite-mass limit particles. Using suitable ansatz, we deduce new explicit spin results gluon four five-point infinite mass processes that exhibit certain exponentiated three-point tree-level factorizations feature no...

In this paper, the cross section for Compton scattering process at finite temperature is calculated. Temperature effects are introduced using Thermofield Dynamics (TFD) formalism. It a real-time quantum field theory. Our result shows that thermal become relevant as increases. A comparison between TFD and closed-time path results presented.

I discuss recent progress in the theory of exclusive meson production and Compton scattering, focusing on hard-scattering factorization and on the dipole formalism.

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...
