Sparticle masses in deflected mirage mediation
Kiwoon Choi, Kwang Sik Jeong, Shuntaro Nakamura +2
We discuss the sparticle mass patterns that can be realized in deflected mirage mediation scenario of supersymmetry breaking, in which the moduli, anomaly, and gauge mediations all…
Axionic Mirage Mediation
Shuntaro Nakamura, Ken-ichi Okumura, Masahiro Yamaguchi
In this talk, we propose a model of mirage mediation, in which Peccei-Quinn symmetry is incorporated. In this \textit{axionic mirage mediation}, it is shown that the Peccei-Quinn s…
Axionic Mirage Mediation
Shuntaro Nakamura, Ken-ichi Okumura, Masahiro Yamaguchi
Although the mirage mediation is one of the most plausible mediation mechanisms of supersymmetry breaking, it suffers from two crucial problems. One is the μ-/B μ-problem and the s…
A Note on Polonyi Problem
Shuntaro Nakamura, Masahiro Yamaguchi
We reinvestigate the cosmological Polonyi problem in the case where the Polonyi mass is . Such a large supersymmetry breaking scale implies that the Polon…
Gravitinos from Heavy Scalar Decay
Takehiko Asaka, Shuntaro Nakamura, Masahiro Yamaguchi
Cosmological issues of the gravitino production by the decay of a heavy scalar field are examined, assuming that the damped coherent oscillation of the scalar once dominates th…
Gravitino Production from Heavy Moduli Decay and Cosmological Moduli Problem Revived
Shuntaro Nakamura, Masahiro Yamaguchi
The cosmological moduli problem for relatively heavy moduli fields is reinvestigated. For this purpose we examine the decay of a modulus field at a quantitative level. The modulus…
