On the two-loop contributions to the pion mass
Roland Kaiser
We derive a simplified representation for the pion mass to two loops in three-flavour chiral perturbation theory. For this purpose, we first determine the reduced expressions for t…
The expansion by regions in pi K scattering
Roland Kaiser, Julia Schweizer
We discuss a number of two loop (vertex) integrals relevant for pi K scattering at threshold. As such these are functions of two well separated mass scales, M\_pi/M\_K << 1. The me…
The < S P P > Green function and SU(3) breaking in K_{l3} decays
V. Cirigliano, G. Ecker, M. Eidemuller +3
Using the 1/N_C expansion scheme and truncating the hadronic spectrum to the lowest-lying resonances, we match a meromorphic approximation to the < S P P > Green function onto QCD…
Large N_c in Chiral Resonance Lagrangians
Roland Kaiser
In the first part of the talk, I discussed results on the determination of the ratios of the light quark masses from large N_c chiral perturbation theory, to be described elsewhere…
Isospin violation in e+ e- --> B Bbar
Roland Kaiser, Aneesh V. Manohar, Thomas Mehen
The ratio of the B+ B- and B0 B0bar production rates in e+ e- annihilation is computed as a function of the B meson velocity and BB* pi coupling constant, using a non-relativistic…
Report of the Working Group on Goldstone Bosons
Johan Bijnens, Ada Farilla, Rory Miskimen
An overview is presented of the talks in the working group on Goldstone Bosons. Topics touched on are CP-violation in the Kaon system, rare Kaon decays, -scattering, -meson…
