Chiral Effective Field Theory in the Delta-resonance region
Abstract
I discuss the problem of constructing an effective low-energy theory in the vicinity of a resonance or a bound state. The focus is on the example of the (1232), the lightest resonance in the nucleon sector. Recent developments of the chiral effective-field theory in the -resonance region are briefly reviewed. I conclude with a comment on the merits of the manifestly covariant formulation of chiral EFT in the baryon sector.
