N=1/2 supergravity with matter in four Euclidean dimensions
Tomoya Hatanaka, Sergei V. Ketov
An N=1/2 supergravity in four Euclidean spacetime dimensions, coupled to both vector- and scalar-multiplet matter, is constructed for the first time. We begin with the standard (1,…
C-deformation of Supergravity
T. Hatanaka, S. V. Ketov
A four-dimensional supergravity toy model in an arbitrary self-dual gravi-photon background is constructed in Euclidean space, by freezing out the gravi-photon field strength in th…
N=1/2 supersymmetric four-dimensional non-linear sigma-models from non-anti-commutative superspace
T. Hatanaka, S. V. Ketov, Y. Kobayashi +1
The component structure of a generic N=1/2 supersymmetric Non-Linear Sigma-Model (NLSM) defined in the four-dimensional (Euclidean) Non-Anti-Commutative (NAC) superspace is investi…
Summing up Non-anti-commutative Kaehler potential
T. Hatanaka, S. V. Ketov, S. Sasaki
We offer a simple non-perturbative formula for the component action of a generic N=1/2 supersymmetric chiral model in terms of an arbitrary number of chiral superfields in four dim…
Non-Anti-Commutative deformation of effective potentials in supersymmetric gauge theories
T. Hatanaka, S. V. Ketov, Y. Kobayashi +1
We studied a nilpotent Non-Anti-Commutative (NAC) deformation of the effective superpotentials in supersymmetric gauge theories, caused by a constant self-dual graviphoton backgrou…
On the universality of goldstino action
Tomoya Hatanaka, Sergei V. Ketov
We find the Goldstino action descending from the N=1 Goldstone-Maxwell superfield action associated with the spontaneous partial supersymmetry breaking, N=2 to N=1, in superspace.…
