Testing clockwork axion with gravitational waves
Cheng-Wei Chiang, Bo-Qiang Lu
We investigate the gravitational waves (GWs) produced from the Peccei-Quinn (PQ) phase transition associated with the clockwork axion. The PQ phase transition can be first-order wh…
Electroweak phase transition confronted with dark matter detection constraints
Cheng-Wei Chiang, Da Huang, Bo-Qiang Lu
We study the type-II first-order electroweak phase transition and dark matter (DM) phenomenology in both real and complex singlet extensions of SM. In the real singlet extension wi…
Evidence of a simple dark sector from XENON1T excess
Cheng-Wei Chiang, Bo-Qiang Lu
We propose that the nearly massless dark photons produced from the annihilation of keV dark fermions in the Galaxy can induce the excess of electron recoil events recently observed…
First-order electroweak phase transition in a complex singlet model with symmetry
Cheng-Wei Chiang, Bo-Qiang Lu
We consider an extension of the Standard Model with a complex singlet scalar, where a global symmetry is explicitly broken to symmetry. We study the two-step…
Constraining primordial black holes in dark matter with kinematics of dwarf galaxies
Bo-Qiang Lu, Yue-Liang Wu
We propose that the kinematical observations of dwarf galaxies can be used to constrain the primordial black hole's (PBH) abundance in dark matter since the presence of primordial…
Damping of gravitational waves in a viscous Universe and its implication for dark matter self-interactions
Bo-Qiang Lu, Da Huang, Yue-Liang Wu +1
It is well known that a gravitational wave (GW) experiences the damping effect when it propagates in a fluid with nonzero shear viscosity. In this paper, we propose a new method to…
