More on DBI action in 4D supergravity
Shuntaro Aoki, Yusuke Yamada
We construct a Dirac-Born-Infeld (DBI) action coupled to a two-form field in four dimensional supergravity. Our superconformal formulation of the action shows a uni…
Note on "Equivalence Between Different Auxiliary Field Formulations of Supergravity Coupled to Matter"
Shuntaro Aoki, Yusuke Yamada
In the version 1 of this paper, we claimed that 4D supergravity formulations with different auxiliary fields can be unified using U(1) gauge symmetry, whose gauge supe…
Abelian tensor hierarchy in 4D conformal supergravity
Shuntaro Aoki, Tetsutaro Higaki, Yusuke Yamada +1
We consider Abelian tensor hierarchy in four-dimensional supergravity in the conformal superspace formalism, where the so-called covariant approach is used to antisymm…
DBI action of real linear superfield in 4D conformal supergravity
Shuntaro Aoki, Yusuke Yamada
We construct the Dirac-Born-Infeld (DBI) action of a real linear multiplet in 4D supergravity. Based on conformal supergravity, we derive the general condition unde…
