Radiative corrections in K --> 3 pi decays
M. Bissegger, A. Fuhrer, J. Gasser +2
We investigate radiative corrections to K --> 3 pi decays. In particular, we extend the non-relativistic framework developed recently to include real and virtual photons and show t…
Cusps in K_L --> 3 pi decays
M. Bissegger, A. Fuhrer, J. Gasser +2
The pion mass difference generates a pronounced cusp in K --> 3 pi decays, the strength of which is related to the pi pi S-wave scattering lengths. We apply an effective field theo…
Hyperon decay form factors in chiral perturbation theory
Andre Lacour, Bastian Kubis, Ulf-G. Meißner
We present a complete calculation of the SU(3)-breaking corrections to the hyperon vector form factors up to O(p^4) in covariant baryon chiral perturbation theory. Partial higher-o…
Investigation of a0-f0 mixing
Christoph Hanhart, Bastian Kubis, Jose R. Pelaez
We investigate the isospin-violating mixing of the light scalar mesons a0(980) and f0(980) within the unitarized chiral approach. Isospin-violating effects are considered to leadin…
An introduction to chiral perturbation theory
Bastian Kubis
A brief introduction to the low-energy effective field theory of the standard model, chiral perturbation theory, is presented.
Aspects of radiative K^+_e3 decays
Bastian Kubis, Eike H. Müller, Jürg Gasser +1
We re-investigate the radiative charged kaon decay K+- --> pi0 e+- nu_e gamma in chiral perturbation theory, merging the chiral expansion with Low's theorem. We thoroughly analyze…
