Cosmological Phase Transitions in Composite Higgs Models
Kohei Fujikura, Yuichiro Nakai, Ryosuke Sato +1
We investigate cosmological phase transitions in various composite Higgs models consisting of four-dimensional asymptotically-free gauge field theories. Each model may lead to a co…
Quantum corrections to the spin-independent cross section in the inert Higgs doublet model
Tomohiro Abe, Ryosuke Sato
The inert Higgs doublet model is an extension of the standard model with an extra scalar doublet. The extra doublet is odd while all the other particles are even, thus…
Quantum corrections to the spin-independent cross section of the inert doublet dark matter
Tomohiro Abe, Ryosuke Sato
The inert Higgs doublet model contains a stable neutral boson as a candidate of dark matter. We calculate cross section for spin-independent scattering of the dark matter on nucleo…
Neutrinoful Universe
Tetsutaro Higaki, Ryuichiro Kitano, Ryosuke Sato
The Standard Model of particle physics fails to explain the important pieces in the standard cosmology, such as inflation, baryogenesis, and dark matter of the Universe. We conside…
LHC Reach of Low Scale Gauge Mediation with Perturbatively Stable Vacuum
Ryosuke Sato, Satoshi Shirai
Very light gravitino scenario m_{3/2} < 16 eV is very interesting, since there is no cosmological problem. However in such a scenario, stability of the vacuum is an important issue…
