OSp supergroup manifolds, superparticles and supertwistors
Igor Bandos, Jerzy Lukierski, Christian Preitschopf +1
We construct simple twistor-like actions describing superparticles propagating on a coset superspace OSp(1|4)/SO(1,3) (containing the D=4 anti-de-Sitter space as a bosonic subspace…
Conformal Field Theory in Conformal Space
C. R. Preitschopf, M. A. Vasiliev
We present a new framework for a Lagrangian description of conformal field theories in various dimensions based on a local version of d+2-dimensional conformal space. The results i…
Dual Actions for Chiral Bosons
Alexey Maznytsia, Christian R. Preitschopf, Dmitri Sorokin
We study duality properties of actions for chiral boson fields in various space-time dimensions using D=2 and D=6 cases as examples. As a result we get dual covariant formulations…
The Superalgebraic Approach to Supergravity
C. R. Preitschopf, M. A. Vasiliev
We formulate classical actions for N=1 supergravity in D=(1,3) as a gauge theory of OSp(1|4). One may choose the action such that it does not include a cosmological term.
Duality of Self-Dual Actions
Alexey Maznytsia, Christian Preitschopf, Dmitri Sorokin
Using examples of a D=2 chiral scalar and a duality-symmetric formulation of D=4 Maxwell theory we study duality properties of actions for describing chiral bosons. In particular,…
On a possible new R^2 theory of supergravity
Tobias Hurth, Peter van Nieuwenhuizen, Andrew Waldron +1
We consider a new MacDowell-Mansouri R^2-type of supergravity theory, an extension of conformal supergravity, based on the superalgebra Osp(1|8). Invariance under local symmetries…
