Quenched and unquenched chiral perturbat
✍ P.H. Damgaard 📂 Article 📅 2004 🏛 Elsevier Science 🌐 English ⚖ 627 KB

The chiral limit of finite-volume &CD is the e-regime of the theory. We discuss how this regime can be used for determining low-energy observables of QCD by means of comparisons between lattice simulations and quenched and unquenched chiral perturbation theory. The quenched theory suffers in the e-r

The temperature evolution of the chiral condensates in a gas made of pions, kaons and etas is studied within the framework of SU(2) and SU(3) Chiral Perturbation Theory. We describe the temperature dependence of the quark condensates by using the meson meson scattering phase shifts in a second order
