Toshiya Suzuki (Hokkaido U.)
TL;DR
This paper proves the kappa-symmetry of a supersymmetric, SL(2;Z)-covariant D3-brane action within an on-shell type-IIB supergravity background, extending previous formulations.
Contribution
It provides a rigorous proof of kappa-symmetry for the supersymmetric D3-brane action with SL(2;Z) covariance, advancing understanding of brane dynamics in supergravity.
Findings
Kappa-symmetry is established for the proposed action.
The action is shown to be consistent with on-shell supergravity backgrounds.
The work extends the theoretical framework of SL(2;Z)-covariant brane actions.
Abstract
We consider a supersymmetric extension of the SL(2;Z)-covariant D3-brane action proposed by Nurmagambetov, and prove its kappa-symmetry in an on-shell type-IIB supergravity background.
