Gauge Mediation Models with Vectorlike Matters at the LHC
Motoi Endo, Koichi Hamaguchi, Kazuya Ishikawa +2
Gauge mediation model with vectorlike matters (V-GMSB) is one of the few viable SUSY models that explains the 126 GeV Higgs boson mass and the muon anomalous magnetic moment simult…
Constraints on Hidden Photon Models from Electron g-2 and Hydrogen Spectroscopy
Motoi Endo, Koichi Hamaguchi, Go Mishima
The hidden photon model is one of the simplest models which can explain the anomaly of the muon anomalous magnetic moment (g-2). The experimental constraints are studied in detail,…
Scalar Decay into Gravitinos in the Presence of D-term SUSY Breaking
Motoi Endo, Koichi Hamaguchi, Takahiro Terada
Scalar decay into gravitinos is studied in the presence of D-term supersymmetry (SUSY) breaking. The gravitinos produced by the decay of coherent oscillations of scalar fields, suc…
Vacuum Stability Bound on Extended GMSB Models
Motoi Endo, Koichi Hamaguchi, Sho Iwamoto +1
Extensions of GMSB models were explored to explain the recent reports of the Higgs boson mass around 124-126 GeV. Some models predict a large mu term, which can spoil the vacuum st…
Stau-catalyzed d-t Nuclear Fusion
Koichi Hamaguchi, Tetsuo Hatsuda, Masayasu Kamimura +1
The gravitino of mass 10-100 GeV is a well motivated scenario in supergravity. If the stau is the next lightest supersymmetry particle, its life-time becomes order of se…
Higgs mass and muon anomalous magnetic moment in the U(1) extended MSSM
Motoi Endo, Koichi Hamaguchi, Sho Iwamoto +2
We study phenomenological aspects of the MSSM with extra U(1) gauge symmetry. We find that the lightest Higgs boson mass can be increased up to 125 GeV, without introducing a large…
