The equivalence between the operator approach and the path integral approach for quantum mechanical non-linear sigma models
Jan de Boer, Bas Peeters, Kostas Skenderis +1
We give background material and some details of calculations for two recent papers [1,2] where we derived a path integral representation of the transition element for supersymmetri…
On the renormalizability and unitarity of the Curci-Ferrari model for massive vector bosons
Jan de Boer, Kostas Skenderis, Peter van Nieuwenhuizen +1
We prove the renormalizability of the Curci-Ferrari model with and without auxiliary fields using BRST methods. In both cases we find 5 factors instead of 3. We verify our resu…
Loop calculations in quantum-mechanical non-linear sigma models sigma models with fermions and applications to anomalies
Jan de Boer, Bas Peeters, Kostas Skenderis +1
We construct the path integral for one-dimensional non-linear sigma models, starting from a given Hamiltonian operator and states in a Hilbert space. By explicit evaluation of the…
Loop calculations in quantum-mechanical non-linear sigma models
Jan de Boer, Bas Peeters, Kostas Skenderis +1
By carefully analyzing the relations between operator methods and the discretized and continuum path integral formulations of quantum-mechanical systems, we have found the correct…
