Reheating in Chaotic D-Term Inflation
Teruhiko Kawano, Masahide Yamaguchi
A simple model is discussed to give rise to successful reheating in chaotic D-term inflation with a quadratic inflaton potential, introducing a trilinear coupling in the Kähler pot…
Schnabl's Solution and Boundary States in Open String Field Theory
Teruhiko Kawano, Isao Kishimoto, Tomohiko Takahashi
We discuss that Schnabl's solution is an off-shell extension of the boundary state describing a D-brane in the closed string sector. It gives the physical meaning of the gauge inva…
Gauge Invariant Overlaps for Classical Solutions in Open String Field Theory
Teruhiko Kawano, Isao Kishimoto, Tomohiko Takahashi
We calculate gauge invariant observables for Schnabl's solution with analytic method and with the level truncation approximation. We also compute them for the numerical solution in…
New D-term chaotic inflation in supergravity and leptogenesis
Kenji Kadota, Teruhiko Kawano, Masahide Yamaguchi
We present a new model of D-term dominated chaotic inflation in supergravity. The F-flat direction present in this model is lifted by the dominant D-term, which leads to chaotic in…
