WIMP dark matter in the parity solution to the strong CP problem
Junichiro Kawamura, Shohei Okawa, Yuji Omura +1
We extend the Standard Model (SM) with parity symmetry, motivated by the strong CP problem and dark matter. In our model, parity symmetry is conserved at high energy by introducing…
Stochastic Gravitational Waves from Particle Origin
Kazunori Nakayama, Yong Tang
We propose that there may be a substantial stochastic gravitational wave background from particle origin, mainly from the gravitational three-body decay of the inflaton. The emitte…
Inflation in gauge theory of gravity with local scaling symmetry and quantum induced symmetry breaking
Yong Tang, Yue-Liang Wu
Motivated by the gauge theory of gravity with local scaling symmetry proposed recently in 1712.04537 and 1506.01807, we investigate whether the scalar field therein can be responsi…
Production of Purely Gravitational Dark Matter
Yohei Ema, Kazunori Nakayama, Yong Tang
In the purely gravitational dark matter scenario, the dark matter particle does not have any interaction except for gravitational one. We study the gravitational particle productio…
Axion-Photon Conversion and Effects on 21cm Observation
Takeo Moroi, Kazunori Nakayama, Yong Tang
Recently the EDGES experiment reported an enhanced 21cm absorption signal in the radio wave observation, which may be interpreted as either anomalous cooling of baryons or heating…
