Extra Matters Decree the Relatively Heavy Higgs of Mass about 125 GeV in the Supersymmetric Model
Takeo Moroi, Ryosuke Sato, Tsutomu T. Yanagida
We show that the Higgs mass about 125 GeV is easily realized in supersymmetric model with extra matters, simultaneously explaining the anomaly in the muon anomalous magnetic moment…
Imprints of Cosmic Phase Transition in Inflationary Gravitational Waves
Ryusuke Jinno, Takeo Moroi, Kazunori Nakayama
We discuss the effects of cosmic phase transition on the spectrum of primordial gravitational waves generated during inflation. The energy density of the scalar condensation respon…
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…
Boltzmann equation for non-equilibrium particles and its application to non-thermal dark matter production
Koichi Hamaguchi, Takeo Moroi, Kyohei Mukaida
We consider a scalar field (called ) which is very weakly coupled to thermal bath, and study the evolution of its number density. We use the Boltzmann equation derived from the…
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…
SUSY CP Problem in Gauge Mediation Model
Takeo Moroi, Norimi Yokozaki
SUSY CP problem in the gauge mediation supersymmetry breaking model is reconsidered. We pay particular attention to two sources of CP violating phases whose effects were not seriou…
Domain Walls and Gravitational Waves after Thermal Inflation
Takeo Moroi, Kazunori Nakayama
Thermal inflation is an attractive solution to the cosmological moduli problem. However, domain walls may be formed after thermal inflation and some mechanisms are needed to elimin…
Studying Very Light Gravitino at the ILC
Shigeki Matsumoto, Takeo Moroi
A collider signal with a stable gravitino of eV mass at the International Linear Collider (ILC) experiment is investigated. Such a light gravitino is generally predic…
Cosmological constraints on dark matter models with velocity-dependent annihilation cross section
Junji Hisano, Masahiro Kawasaki, Kazunori Kohri +3
We derive cosmological constraints on the annihilation cross section of dark matter with velocity-dependent structure, motivated by annihilating dark matter models through Sommerfe…
