My aim is to review some recent progress on the understanding of low-energy baryon structure by means of an effective field theory of QCD, the Lorentz covariant chiral perturbation theory. I will first introduce the motivation for a resummation of relativistic corrections, as compared with the strategy followed in heavy-baryon ChPT. Subsequently, I will discuss the application of the ChPT formalism to the description of various observables such as the baryon-octet magnetic moments or the electromagnetic structure of decuplet resonances. Finally, I present some applications to the extrapolation and interpretation of recent lattice QCD results on the baryon masses.
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
