On Wess-Zumino gauge
Kazunari Shima, Motomu Tsuda
In the relation between the linear (L) supersymmetry (SUSY) representation and the nonlinear (NL) SUSY representation we discuss the role of the Wess-Zumino gauge. We show in two d…
Modulated inflation from kinetic term
Tomohiro Matsuda
We study modulated inflation from kinetic term. Using the Mukhanov-Sasaki variable, it is possible to determine how mixing induced by the kinetic term feeds the curvature perturbat…
On N = 2 superfield for N = 2 vector supermultiplet in two dimensional spacetime
Kazunari Shima, Motomu Tsuda
We focus on the superfield formulation for a N = 2 vector supermultiplet in two dimensional spacetime and explicitly show that the Wess-Zumino gauge condition for a N = 2 superfiel…
Modulated Inflation
Tomohiro Matsuda
We have studied modulated inflation that generates curvature perturbation from light-field fluctuation. As discussed in previous works, even if the fluctuation of the inflaton itse…
Hilltop Curvatons
Tomohiro Matsuda
We study ``hilltop'' curvatons that evolve on a convex potential. Hilltop curvatons evolving on the Hubble-induced potential are generic if supergravity is assumed in the theory. W…
