Remarks on NN → NNπ beyond leading order
In recent years a two-scale expansion was established to study reactions of the type NN → NNπ within chiral perturbation theory. Then the diagrams of some subclasses that are invariant under the choice of the pion field no longer appear at the same chiral order. In this letter we show that the proposed expansion still leads to well defined results. We also discuss the appropriate choice of the ...
متن کاملStatus of Effective Field Theory of Nn Scattering
I review recent progress in developing a systematic power counting scheme for scattering processes involving more than one nucleon. 1. Why effective field theory? There exist many nucleon-nucleon potentials which reproduce phase shifts and nuclear properties with remarkable accuracy (an extensive reference list can be found in Ref. [1]). Three fundamental features are shared by these potential ...
متن کاملThe Potential of Effective Field Theory in NN Scattering
We study an effective field theory of interacting nucleons at distances much greater than the pion’s Compton wavelength. In this regime the NN potential is conjectured to be the sum of a delta function and its derivatives. The question we address is whether this sum can be consistently truncated at a given order in the derivative expansion, and systematically improved by going to higher orders....
متن کاملImproving the Convergence of NN Effective Field Theory
We study a low-energy effective field theory (EFT) describing the NN system in which all exchanged particles are integrated out. We show that fitting the residue of the S1 amplitude at the deuteron pole, rather than the S1 effective range, dramatically improves the convergence of deuteron observables in this theory. Reproducing the residue ensures that the tail of the deuteron wave function, wh...
متن کاملEffective field theory contribution to charge symmetry breaking NN scattering
The effect of isospin breaking pion s-wave rescattering is included in elastic NN scattering at low energies using effective field theory. Although this mechanism gave a large contribution to charge symmetry breaking in np → dπ, the effect is rather small in pp vs. nn scattering parameters and in the H-He binding energy difference. This smallness is caused by large cancellation of the up-down q...
