On the Radiative Pion Decay
Rene Unterdorfer, Hannes Pichl
A reanalysis of the radiative pion decay together with the calculation of the radiative corrections within chiral perturbation theory (CHPT) is performed. The amplitude of this dec…
Electromagnetic radiative corrections to pionic beta decay π^+ to π^0 e^+ ν_e
Hannes Pichl
Pionic beta decay π^+ to π^0 e^+ ν_e is analyzed in chiral perturbation theory with virtual photons and leptons. All electromagnetic corrections up to order e^2 p^2 are taken into…
The pionic beta decay in chiral perturbation theory
V. Cirigliano, M. Knecht, H. Neufeld +1
Within the framework of chiral perturbation theory with virtual photons and leptons, we present an updated analysis of the pionic beta decay including all electromagnetic contribut…
The CP-violating asymmetry in K_L -> pi+ pi- e+ e-
G. Ecker, H. Pichl
We update the theoretical analysis of the CP-violating asymmetry in the decay K_L -> pi+ pi- e+ e-, relying on chiral perturbation theory and on the most recent phenomenological in…
K->pipie+e- decays and chiral low-energy constants
Hannes Pichl
The branching ratios of the measured decay and of the still unmeasured decay are calculated to next-to-leading order in Chiral Perturbatio…
