Polonyi-Starobinsky supergravity with inflaton in a massive vector multiplet with DBI and FI terms
Hiroyuki Abe, Yermek Aldabergenov, Shuntaro Aoki +1
We propose the Starobinsky-type inflationary model in the matter-coupled four-dimensional supergravity with the massive vector multiplet that has inflaton (scalaron) and gold…
Massive vector multiplet with Dirac-Born-Infeld and new Fayet-Iliopoulos terms in supergravity
Hiroyuki Abe, Yermek Aldabergenov, Shuntaro Aoki +1
We propose a four-dimensional N = 1 supergravity-based Starobinsky-type inflationary model in terms of a single massive vector multiplet, whose action includes the Dirac-Born-Infel…
superfield description of BPS solutions in 6D gauged SUGRA with 3-branes
Hiroyuki Abe, Shuntaro Aoki, Sosuke Imai +1
We provide superfield description of BPS backgrounds in six-dimensional supergravity (6D SUGRA) with 3-branes, which is compactified on a two-dimensional space. The br…
