The Effective Field Theory of Vector-Tensor Theories
Katsuki Aoki, Mohammad Ali Gorji, Shinji Mukohyama +1
We investigate a systematic formulation of vector-tensor theories based on the effective field theory (EFT) approach. The input of our EFT is that the spacetime symmetry is spontan…
Inflation with
Mohammad Ali Gorji, Hayato Motohashi, Shinji Mukohyama
We investigate a novel single field inflationary scenario which allows a transition between a slow-roll k-inflation with of order unity and a ghost inflation with $ c_{…
Dark Matter from Entropy Perturbations in Curved Field Space
Hassan Firouzjahi, Mohammad Ali Gorji, Shinji Mukohyama +1
The accumulated energy density of the excited entropy modes in multiple field inflationary scenarios can play the role of dark matter. In the usual case of a flat field space witho…
