Mass spectrum and elastic scattering in the massive SU(2)_f Schwinger model on the lattice
C. Gutsfeld, H. A. Kastrup, K. Stergios
We calculate numerically scattering phases for elastic meson-meson scattering processes in the strongly coupled massive Schwinger-model with an SU(2) flavour symmetry. These calcul…

Meson-meson scattering in the massive Schwinger model --- a status report
C. Gutsfeld, H. A. Kastrup, K. Stergios +1
We discuss the possibility of extracting phase shifts from finite volume energies for meson-meson scattering, where the mesons are fermion-antifermion bound states of the massive S…

Calculation of Universal Amplitude Ratios in three-loop order
Christoph Gutsfeld, Jens Kuester, Gernot Muenster
For the universality class of three-dimensional Ising systems the ratio of the high- and low-temperature amplitudes for the correlation length and for the susceptibility are univer…
