Decay widths and scattering processes in massive QED
C. Adam
Using mass perturbation theory, we infer the bound-state spectrum of massive QED and compute some decay widths of unstable bound states. Further, we discuss scattering processe…
Consistent and covariant commutator anomalies in the chiral Schwinger model
C. Adam
We derive all covariant and consistent divergence and commutator anomalies of chiral QED within the framework of canonical quantization of the fermions. Further, we compute the…
Investigation of anomalous axial QED
C. Adam
Although axial QED suffers from a gauge anomaly, gauge invariance may be maintained by the addition of a nonlocal counterterm. Such nonlocal conterterms, however, are expected to r…
Scattering processes in the massive Schwinger model
C. Adam
We derive the (matrix-valued) Feynman rules of the mass perturbation theory and use it for the resummation of the -point functions with the help of the Dyson-Schwinger equations…
