Superspace or One Thousand and One Lessons in Supersymmetry
The 1983 book, free at last, with corrections and bookmarks. From the original troff, but now with CM (TeX) fonts.
Classical superstring mechanics
- W. Siegel
- 13 January 1986
Abstract We describe the classical mechanics of the superstring in both hamiltonian and lagrangian formulations, including massless external fields. The formulation is a modification of that of Green… Expand
Bouncing universes in string-inspired gravity
We consider the effects on cosmology of higher-derivative modifications of (effective) gravity that make it asymptotically free without introducing ghosts. The weakening of gravity at short distances… Expand
Supersymmetric Dimensional Regularization via Dimensional Reduction
- W. Siegel
- 18 June 1979
We introduce a modified form of dimensional regularization which manifestly preserves gauge invariance, unitarity, and global supersymmetry. The prescription is that the action which results from… Expand
Improved Methods for Supergraphs
We introduce some new techniques into superfield perturbation theory which allow considerable simplifications in calculations. As a result, we show that all contributions to the effective action can… Expand
Supertwistor space for 6D maximal super Yang-Mills
Abstract6 dimensional maximal super Yang-Mills on-shell amplitudes are formulated in superspace using 6 dimensional spinors. The 3,4,5-point tree amplitudes are obtained by supersymmetrizing their… Expand
A bstractWe develop doubled-coordinate field theory to determine the α′ corrections to the massless sector of oriented bosonic closed string theory. Our key tool is a string current algebra of free… Expand
Variant superfield representations
Abstract We discuss some variant superfield representations which can arise by the replacement of some of the usual fields in a multiplet with p-form gauge fields.
Gauge spinor superfield as scalar multiplet
- W. Siegel
- 27 August 1979
Abstract A chiral spinor superfield, with an appropriate gauge invariance, describes a scalar multiplet consisting of a scalar, an antisymmetric-tensor gauge field, a Weyl spinor, and no auxiliary… Expand
