The application of the effective field theory (EFT) method to nuclear systems is reviewed. The roles of degrees of freedom, QCD symmetries, power counting, renormalization, and potentials are discussed. EFTs are constructed for the various energy regimes of relevance in nuclear physics, and are used in systematic expansions to derive nuclear forces in terms of a number of parameters that embody information about QCD dynamics. Two-, three-, and many-nucleon systems, including external probes, are considered. * Commissioned for Prog. Part. Nucl. Phys.

“…First, over the last decade fairly precise differential and total cross section data have been obtained at MAMI [3,4,5] and SAL [6,7,8]. A further experiment involving linearly polarized photons was performed at MAMI, which not only improved the differential cross sections but also gave the first determination of the photon asymmetry [9].…”

Aspects of near-threshold neutral pion photoproduction off protons

2001

We investigate near threshold neutral pion photoproduction off protons to fourth order in heavy baryon chiral perturbation theory in the light of the new data from MAMI. We show that the unitarity cusp at the secondary π + n threshold is in agreement with expectations from the final state theorem. We also analyze the fourth order corrections to the P-wave low-energy theorems and show that potentially large ∆-isobar contributions are cancelled by sizeable pion loop effects. This solidifies the parameter free third order predictions, which are in good agreement with the data.
