Quantum Supersymmetric Ghosts
Florin Constantinescu
We work out the quantization of the massless vector field by introducing quantum supersymmetric ghosts. We prove positivity in the physical Fock space.
Causal Perturbation Theory for the Supersymmetric Wess-Zumino Model
Florin Constantinescu
We illustrate the causal perturbation and causal renormalization method (the Epstein-Glaser method) for the case of the supersymmetric Wess-Zumino model. Our study is based on the…
Krein structure of supersymmetry
Florin Constantinescu
We present supersymmetric positive definite scalar products together with natural Krein structures of supersymmetries.
Quantum field components of supersymmetric multiplets
Florin Constantinescu, Gunter Scharf
We adress the problem of Fock space representations of (free) multiplet component fiels encountered in supersymmetric quantum field theory insisting on positivity and causality. We…
Quantized hermitian superfields
Florin Constantinescu, Markus Gut, Gunter Scharf
We analyse the algebras generated by free component quantum fields together with the susy generators . Restricting to hermitian fields we first construct the scalar field…
Causal Approach to Supersymmetry: Chiral Superfields
Florin Constantinescu, Gunter Scharf
We construct quantized free superfields and represent them as operator-valued distributions in Fock space starting with Majorana fields. The perturbative construction of the S-matr…
