Is soft breaking of BRST symmetry consistent?

Lavrov, Peter; Lechtenfeld, Olaf; Reshetnyak, Alexander (New York, NY : Springer International Publishing, 2011)

A definition of soft breaking of BEST symmetry in the field-antifield formalism is proposed, valid for general gauge theories and arbitrary gauge fixing. The Ward identities for the generating functionals of Green's functions ...
Is the Nicolai map unique?

Lechtenfeld, Olaf; Rupprecht, Maximilian (Berlin, Heidelberg : Springer, 2022)

The Nicolai map is a field transformation that relates supersymmetric theories at finite couplings g with the free theory at g = 0. It is obtained via an ordered exponential of the coupling flow operator integrated from 0 ...
