Topics in Chiral Perturbation Theory
I consider some selected topics in chiral perturbation theory (CHPT). For the meson sector, emphasis is put on processes involving pions in the isospin zero S-wave which require multi-loop calculations. The advantages and shortcomings of heavy baryon CHPT are discussed. Some recent results on the structure of the baryons are also presented.
متن کاملTopics in baryon chiral perturbation theory
Baryon chiral perturbation theory can be used as a tool to analyze properties of excited baryons in lattice QCD. I discuss some recent developments in this cross-disciplinary field. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.
متن کاملChiral Perturbation Theory
Abstract. The charged kaon decay channel K l3γ allows for studies of direct CP violation, possibly due to non-standard mechanisms, with the help of T -odd correlation variables. In order to be able to extract a CP -violating signal from experiment, it is necessary to understand all possible Standard Model phases that also produce T -odd asymmetries. We complement earlier studies by considering ...
متن کاملApplied Chiral Perturbation Theory
I consider some selected topics in chiral perturbation theory (CHPT) as probed at colliders such as DAΦNE. Emphasis is put on processes involving pions in the isospin zero S-wave which require multi-loop calculations. These include the scalar form factor of the pion, two–photon fusion into pion pairs and Kl4–decays. The physics of the chiral anomaly is briefly touched upon INVITED LECTURE SUMME...
متن کاملChiral Perturbation Theory
A short overview of the current state of Chiral Perturbation Theory is given. This includes a description of the basic assumptions, the usefulness of the external field method is emphasized using a simple lowest order example. Then at next-to-leading order the determination of the parameters is discussed. We also present the status of calculations at O(p6). Finally I present the extension into ...
