✦ Synopsis

The differential cross section for y-deuteron Compton scattering is computed to next-to-leading order (NLO) in an effective field theory that describes nucleon-nucleon interactions below the pion production threshold. Contributions at NLO include the nucleon isoscalar electric polarizability from its 1/m~ behavior in the chiral limit. The parameter-free prediction of the y-deuteron differential cross section at NLO is in good agreement with data. @ 1998 Elsevier Science B.V.

We study Compton scattering in systems with A = 1 and 2 using chiral perturbation theory up to fourth order. For the proton we fit the two undetermined parameters in the O(Q 4 ) γp amplitude of McGovern to experimental data in the region ω, √ |t| 180 MeV, obtaining a χ 2 /d.o.f. of 133/113. This yie

Effective field theory, including pions, provides a consistent and systematic description of nucleon-nucleon strong interactions up to center-of-mass momentum p ~ 300 MeV per nucleon. We describe the inclusion of hadronic parity violation into this effective field theory and find an analytic form fo
