BRST treatment of zero modes for the worldline formalism in curved space
Fiorenzo Bastianelli, Olindo Corradini, Andrea Zirotti
One-loop quantities in QFT can be computed in an efficient way using the worldline formalism. The latter rests on the ability of calculating 1D path integrals on the circle. In thi…

Dimensional regularization for N=1 susy sigma models and the worldline formalism
Fiorenzo Bastianelli, Olindo Corradini, Andrea Zirotti
We generalize the worldline formalism to include spin 1/2 fields coupled to gravity. To this purpose we first extend dimensional regularization to supersymmetric nonlinear sigma mo…
