Radiative Non-Leptonic Kaon Decays
G. D'Ambrosio, G. Ecker, G. Isidori +1
We investigate to what extent DANE will be able to test the Standard Model in the confinement regime with radiative kaon decays. We concentrate on processes which can be detecte…
What is a low-energy theorem ?
G. Ecker, U. -G. Meissner
We discuss the meaning of low-energy theorems (LETs) in the framework of the effective field theory of the standard model. Particular emphasis is put on the LET for neutral pion ph…
The pion-nucleon interaction as an effective field theory
G. Ecker
After a brief survey of effective field theories, the linear sigma model is discussed as a prototype of an effective field theory of the standard model below the chiral-symmetry-br…
Chiral invariant renormalization of the pion--nucleon interaction
G. Ecker
The leading divergences of the generating functional for Green functions of quark currents between one--nucleon states are calculated with heat kernel techniques. The results allow…
