Elastic Compton scattering from 3He and the role of the Delta

. We report observables for elastic Compton scattering from 3 He in Chiral Effective Field Theory with an explicit Δ ( 1232 ) degree of freedom ( χ EFT) for energies between 50 and 120MeV. The γ 3 He amplitude is complete at N 3 LO, O ( e 2 δ 3 ) , and in general converges well order by order. It in...
