  1. Generalization of Supergravity General holomorphic pure supergravity and its cosmology 19th International Summer Institute on Phenomenology of Elementary Particles and Cosmology Takahiro Terada Univ. of Tokyo, Japan Sergei V. Ketov and TT, JHEP07(2013)127, arXiv:1304.4319 [hep-th] Supersymmetrization of Modified Gravity

  2. Planck collaboration, arXiv:1303.5082 Many reasons to do that!! • pure theoretical interests • stringy/quantum corrections • potential applications to pheno • application to inflation • to embed modified gravity into fundamental theory, etc.

  3. Positioning of the work Supersymmetrization Simple NEW NEW General Bosonic sector

  4. New action for supergravity where is a holomorphic function. +H.c.

  5. f(R) gravity • Scalar-tensor gravity • scalar-tensor gravity with Weyl tensor gravity and Inflation • f(R,C) gravity Starobinsky model + correction term () as a simple non-trivial example: where is the inflaton mass and is a coupling constant. equivalent equivalent

  7. 19th International Summer Institute on Phenomenology of Elementary Particles and Cosmology General holomorphic pure supergravity and its cosmology Takahiro Terada Univ. of Tokyo, Japan Sergei V. Ketov and TT, JHEP07(2013)127, arXiv:1304.4319 [hep-th] Summary • There are many reasons to study modified supergravity. • We proposed a new type of action for modified gravity and supergravity. • It’s interesting to compare the results with future CMB data.
