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…
Chaotic D-Term Inflation
Teruhiko Kawano
A simple model for chaotic inflation in supergravity is proposed. The model is N=1 supersymmetric massive U(1) gauge theory via the Stuckelberg superfield and gives rise to D-term…
Supersymmetric N=1 Spin(10) Gauge Theory with Two Spinors via a-Maximization
Teruhiko Kawano, Futoshi Yagi
We give a detailed analysis of the superconformal fixed points of four-dimensional N=1 supersymmetric Spin(10) gauge theory with two spinors and vectors by using a-maximization pro…
Gauge Mediation in String Theory
Teruhiko Kawano, Hirosi Ooguri, Yutaka Ookouchi
We show that a large class of phenomenologically viable models for gauge mediation of supersymmetry breaking based on meta-stable vacua can be realized in local Calabi-Yau compacti…
