Auxiliary tensor fields for Sp(2,R) self-duality
Evgeny A. Ivanov, Olaf Lechtenfeld, Boris M. Zupnik
The coset Sp(2,R)/U(1) is parametrized by two real scalar fields. We generalize the formalism of auxiliary tensor (bispinor) fields in U(1) self-dual nonlinear models of abelian ga…
SU(4) harmonic superspace and supersymmetric gauge theory
B. M. Zupnik
We consider the harmonic-superspace formalism in the supersymmetry using the harmonics which was earlier applied to the abelian gauge the…
Self-Dual N=2 Born-Infeld Theory Through Auxiliary Superfields
E. A. Ivanov, B. M. Zupnik
There is an evidence that the N=2 Born-Infeld theory with spontaneously broken N=4 supersymmetry exhibits self-duality. We perform a further check of this hypothesis by constructin…
Unifying the PST and the auxiliary tensor field formulations of 4D self-duality
E. A. Ivanov, A. J. Nurmagambetov, B. M. Zupnik
We unify the Lorentz- and O(2) duality-covariant approach to 4D self-dual theories by Pasti, Sorokin and Tonin (PST) with the formulation involving an auxiliary tensor field. We pr…
Bispinor Auxiliary Fields in Duality-Invariant Electrodynamics Revisited: The U(N) Case
E. A. Ivanov, B. M. Zupnik
We update and detail the formulation of the duality-invariant systems of N interacting abelian gauge fields with N auxiliary bispinor fields added. In this setting, the self-dualit…
Auxiliary superfields in N=1 supersymmetric self-dual electrodynamics
Evgeny Ivanov, Olaf Lechtenfeld, Boris Zupnik
We construct the general formulation of N=1 supersymmetric self-dual abelian gauge theory involving auxiliary chiral spinor superfields. Self-duality in this context is just U(N) i…
