Magnetic moment of the Delta(1232)-resonance in chiral effective field theory
Abstract
We perform a relativistic chiral effective field theory calculation of the radiative pion photoproduction (γ p π0 p γ') in the -resonance region, to next-to-leading order in the ``delta-expansion''. This work is aimed at a model-independent extraction of the + magnetic moment from new precise measurements of this reaction. It also predicts the chiral behavior of 's magnetic moment, which can be used to extrapolate the recent lattice QCD results to the physical point.
