Flavour mixings in flux compactifications
Wilfried Buchmuller, Julian Schweizer
A multiplicity of quark-lepton families can naturally arise as zero-modes in flux compactifications. The flavour structure of quark and lepton mass matrices is then determined by 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…
Isospin odd pi K scattering length
J. Schweizer
We make use of the chiral two-loop representation of the pi K scattering amplitude [J. Bijnens, P. Dhonte and P. Talavera, JHEP 0405 (2004) 036] to investigate the isospin odd scat…
Spectrum and decays of hadronic atoms
J. Schweizer
We describe the spectra and decays of pi pi and pi K atoms within a non-relativistic effective field theory. The evaluations of the energy shifts and widths are performed at next-t…

Decay widths and energy shifts of pi pi and pi K atoms
J. Schweizer
We calculate the S-wave decay widths and energy shifts for pi pi and pi K atoms in the framework of QCD+QED. The evaluation - valid at next-to-leading order in isospin symmetry bre…
