Indirect dark matter searches as a probe of degenerate particle spectra
Masaki Asano, Torsten Bringmann, Christoph Weniger
We consider the possibility that the cosmological dark matter consists of particles very close in mass to new colored particles below the TeV scale. While such a scenario is inhere…
Exploring Supersymmetric Model with Very Light Gravitino at the LHC
Masaki Asano, Takumi Ito, Shigeki Matsumoto +1
The low-scale gauge mediation scenario of supersymmetry breaking predicts very light gravitino, which makes the next lightest supersymmetric particle (NLSP) quasi stable. We study…
Focus Point Assisted by Right-Handed Neutrinos
Masaki Asano, Takeo Moroi, Ryosuke Sato +1
The large hadron collider experiments have now reached the focus point region in which the scalar masses are multi-TeV. We study the parameter region of the focus point scenario wh…
Non-anomalous Discrete R-symmetry, Extra Matters, and Enhancement of the Lightest SUSY Higgs Mass
Masaki Asano, Takeo Moroi, Ryosuke Sato +1
We consider low-energy supersymmetric model with non-anomalous discrete R-symmetry. In such a model, to make the R-symmetry non-anomalous, new particles with gauge quantum numbers…
Singlet Boson in Supersymmetric Model as a Mimic of the Standard Model Higgs at the LHC
Masaki Asano, Takeo Moroi, Norimi Yokozaki
We show that the gauge singlet scalar boson in low-energy supersymmetric model may behave as the standard model (SM) Higgs boson if the singlet couples to (heavy) vector-like color…
Discrimination of New Physics Models with the International Linear Collider
Masaki Asano, Tomoyuki Saito, Taikan Suehara +7
The large hadron collider (LHC) is anticipated to provide signals of new physics at the TeV scale, which are likely to involve production of a WIMP dark matter candidate. The inter…
