Renormal-order improvement of the Schwinger mass
Christoph Adam
The massive Schwinger model may be analysed by a perturbation expansion in the fermion mass. However, the results of this mass perturbation theory are sensible only for sufficientl…

Normalization of the chiral condensate in the massive Schwinger model
Christoph Adam
Within mass perturbation theory, already the first order contribution to the chiral condensate of the massive Schwinger model is UV divergent. We discuss the problem of choosing a…

Theta vacuum in different gauges
Christoph Adam
In some recent papers it is claimed that the physical significance of the vacuum angle theta for QCD-like theories depends on the chosen gauge condition. We criticise the arguments…
