Soft Supersymmetry Breaking at Heavy Chiral Threshold
Hiroyuki Matsuura, Hiroaki Nakano, Koichi Yoshioka
We discuss the structure of threshold corrections to soft supersymmetry-breaking parameters at the mass threshold of heavy chiral superfields. Nontrivial dependence on soft paramet…
TeV Scale Mirage Mediation and Natural Little SUSY Hierarchy
Kiwoon Choi, Kwang Sik Jeong, Tatsuo Kobayashi +1
TeV scale mirage mediation has been proposed as a supersymmetry breaking scheme reducing the fine tuning for electroweak symmetry breaking in the minimal supersymmetric extension o…
Mirage unification at TeV scale and natural electroweak symmetry breaking in minimal supersymmetry
Ken-ichi Okumura
We propose a new minimal supersymmetric scenario with virtually no fine-tuning in the electroweak symmetry breaking. It favors light supersymmetric spectrum below a few TeV and pre…
Relic abundance and detection prospects of neutralino dark matter in mirage mediation
Ken-ichi Okumura
We analyze thermal relic abundance of neutralino dark matter and discuss future prospects of its direct and indirect detections in mirage mediation.
Low-energy Variety of Asymmetric SUSY Flavor Structure
Kenzo Inoue, Kentaro Kojima, Koichi Yoshioka
In this letter we study the low-energy phenomenology and cosmological implications of supersymmetric grand unified theory with asymmetric flavor structure, which is suggested by th…
Flavor Symmetry and Vacuum Aligned Mass Textures
Satoru Kaneko, Hideyuki Sawanaka, Takaya Shingai +2
The mass matrix forms of quarks and leptons are discussed in theory with permutation flavor symmetry. The structure of scalar potential is analyzed in case that electroweak doublet…
