These lecture notes include the following topics. Chapter 1 deals with QCD and its global symmetries in the chiral limit, explicit symmetry breaking in terms of the quark masses, and the concept of Green functions and Ward identities reflecting the underlying chiral symmetry. In Chapter 2 the idea of a spontaneous breakdown of a global symmetry is discussed and its consequences in terms of the Goldstone theorem are demonstrated. Chapter 3 deals with mesonic chiral perturbation theory and the… Expand

Abstract.Chiral perturbation theory is the effective field theory of the strong interactions at low energies. We will give a short introduction to chiral perturbation theory for mesons and willExpand
Recent developments in effective field theory
Abstract We will give a short introduction to the one-nucleon sector of chiral perturbation theory and will address the issue of a consistent power counting and renormalization. We will discuss theExpand
Aspects of Meson Condensation
In this work pion and kaon condensation in the framework of chiral perturbation theory is studied. I consider a system at vanishing temperature with nonzero isospin chemical potential and strangenessExpand
Meson Physics in Asymmetric Matter
This paper describes dynamic and thermodynamic (at $T=0$) properties of mesons in asymmetric matter in the framework of Chiral Perturbation Theory. We consider a mesonic system at vanishingExpand
Degeneracy Patterns of Chiral Companions at Finite Temperature
TLDR
This work reviews how different realizations of chiral partner degeneracy arise in different effective theories/models of QCD and discusses the intriguing case in which chiral symmetry restoration involves more than two chiral partners, recently addressed in the literature. Expand
BARYON CHIRAL PERTURBATION THEORY IN MANIFESTLY LORENTZ-INVARIANT FORM
A successful effective field theory program requires besides the most general effective Lagrangian a perturbative expansion scheme for observables in terms of a consistent power counting method. WeExpand
Intriguing aspects of meson condensation
We analyze various aspects of pion and kaon condensation in the framework of chiral perturbation theory. Considering a system at vanishing temperature and varying the isospin chemical potential andExpand
Continuum results for light hadrons from 2+1 flavour Domain Wall QCD
