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…
Inflation in supergravity without Kahler potential
Shuntaro Aoki, Yusuke Yamada
We propose a new class of inflation models in supergravity with higher derivative terms. In those models, the Kähler potential does not contain the inflaton multiplet, but a supers…
Illustrating SUSY breaking effects on various inflation mechanisms
Hiroyuki Abe, Shuntaro Aoki, Fuminori Hasegawa +1
We consider the supersymmetry breaking effects on typical inflation models with different types of Kähler potential. The critical size of supersymmetry-breaking scale, above which…
