Supersymmetry, supergravity, superspace and BRST symmetry in a simple model

Peter van Nieuwenhuizen

We give an introduction to rigid supersymmetry, supergravity and superspace by considering a quantum mechanical model. We analyze the constraints in superspace in this simplified m…

Supergravity as a Yang-Mills theory

Peter van Nieuwenhuizen

We give a simple introduction to ordinary and conformal supergravity, and write their actions as squares of curvatures.

N=4 Superconformal Symmetry for the Covariant Quantum Superstring

P. A. Grassi, P. van Nieuwenhuizen

We extend our formulation of the covariant quantum superstring as a WZNW model with N=2 superconformal symmetry to N=4. The two anticommuting BRST charges in the N=4 multiplet of c…

New developments in the quantization of supersymmetric solitons (kinks, vortices and monopoles)

Anton Rebhan, Peter van Nieuwenhuizen, Robert Wimmer

We discuss the one-loop quantum corrections to the mass M and central charge Z of supersymmetric solitons: the kink, the vortex and the monopole. Contrary to previous expectations…

Gauging Cosets

P. A. Grassi, P. van Nieuwenhuizen

We show how to gauge the set of raising and lowering generators of an arbitrary Lie algebra. We consider SU(N) as an example. The nilpotency of the BRST charge requires constraints…

Harmonic Superspaces from Superstrings

P. A. Grassi, P. van Nieuwenhuizen

We derive harmonic superspaces for N=2,3,4 SYM theory in four dimensions from superstring theory. The pure spinors in ten dimensions are dimensionally reduced and yield the harmoni…
