Auxiliary fields in open gauge theories
N. Djeghloul, A. Meziane, M. Tahiri
We show that for open gauge theories, it is possible to build an off-shell Becchi-Rouet-Stora-Tyutin (BRST) algebra together with an invariant extension of the classical action. Th…
A modified N=2 extended supersymmetry
Nazim Djeghloul, Mohamed Tahiri
A modification of the usual extended N = 2 supersymmetry algebra implementing the two dimensional permutation group is performed. It is shown that one can found a multiplet that fo…
An Alternative Construction of the Quantum Action for Supergravity
N. Djeghloul, M. Tahiri
We develop a method to derive the on-shell invariant quantum action of the supergravity in such a way that the quartic ghost interaction term is explicity determined. First, we rei…
From on-shell to off-shell open gauge theories
N. Djeghloul, M. Tahiri
We present an alternative quantization for irreducible open gauge theories. The method relies on the possibility of modifying the classical BRST operator and the gauge-fixing actio…
