Abstract
We discuss recent applications of the perturbative chiral quark model (PCQM) in the analysis of the structure of baryons. The PCQM is based on an effective Lagrangian, where baryons are described by relativistic valence quarks and a perturbative cloud of Goldstone bosons as required by chiral symmetry. We discuss for example applications to electromagnetic properties of the octet baryons and σ-term physics. Furthermore, we present recent efforts to formulate and apply a manifestly Lorentz covariant chiral quark model, which is consistent with the latest developments in the baryon sector of chiral perturbation theory.
