Cosmology with the Laser Interferometer Space Antenna
Pierre Auclair, David Bacon, Tessa Baker +177
The Laser Interferometer Space Antenna (LISA) has two scientific objectives of cosmological focus: to probe the expansion rate of the universe, and to understand stochastic gravita…
Imprint of Early Dark Energy in Stochastic Gravitational Wave Background
Chia-Feng Chang
Early dark energy that relieves Hubble tension leaves a fingerprint in the primordial stochastic gravitational wave (GW) background that originates from cosmic string network. The…
Gravitational Waves from Global Cosmic Strings and Cosmic Archaeology
Chia-Feng Chang, Yanou Cui
Global cosmic strings are predicted in many motivated extensions to the Standard Model of particle physics, with close connections to axion dark matter physics. Recent studies sugg…
New Perspectives on Axion Misalignment Mechanism
Chia-Feng Chang, Yanou Cui
A zero initial velocity of the axion field is assumed in the conventional misalignment mechanism. We propose an alternative scenario where the initial velocity is nonzero, which ma…
Stochastic Gravitational Wave Background from Global Cosmic Strings
Chia-Feng Chang, Yanou Cui
Global cosmic strings are generically predicted in particle physics beyond the Standard Model, e.g., a post-inflationary global symmetry breaking which may associate with ax…
Flavor Changing Neutral Currents in the Asymmetric Left-Right Gauge Model
Chia-Feng Chang, Ernest Ma
In the extension of the standard model, a minimal (but asymmetric) scalar sector consists of one $SU(2)_R \times U(1)_…
Exploring Spin-3/2 Dark Matter with Effective Higgs Couplings
Chia-Feng Chang, Xiao-Gang He, Jusak Tandean
We study an economical model of weakly-interacting massive particle dark matter (DM) which has spin 3/2 and interacts with the 125-GeV Higgs boson via effective scalar and pseudosc…
Electron Electric Dipole Moment in Mirror Fermion Model with Electroweak Scale Non-sterile Right-handed Neutrinos
Chia-Feng Chang, P. Q. Hung, Chrisna Setyo Nugroho +2
The electric dipole moment of the electron is studied in detail in an extended mirror fermion model with the following unique features of (a) right-handed neutrinos are non-sterile…
Two-Higgs-Doublet-Portal Dark-Matter Models in Light of Direct Search and LHC Data
Chia-Feng Chang, Xiao-Gang He, Jusak Tandean
We explore simple Higgs-portal models of dark matter (DM) with spin 1/2, 3/2, and 1, respectively, applying to them constraints from the LUX and PandaX-II direct detection experime…
Hidden Photon Compton and Bremsstrahlung in White Dwarf Anomalous Cooling and Luminosity Functions
Chia-Feng Chang
We computed the contribution of the Compton and Bremsstrahlung processes with a hidden light neutral boson to the white dwarf G117-B15A anomalous cooling rate, as we…
Lepton Flavor Violating Decays of Neutral Higgses in Extended Mirror Fermion Model
Chia-Feng Chang, Chia-Hung Vincent Chang, Chrisna Setyo Nugroho +1
We perform the one-loop induced charged lepton flavor violating decays of the neutral Higgses in an extended mirror fermion model with non-sterile electroweak-scale right-handed ne…
A global flavor symmetry analysis for with Mixing
Yu-Kuo Hsiao, Chia-Feng Chang, Xiao-Gang He
A large number of new experimental data on decay into two light pesudoscalar () mesons have been collected by the LHCb collaboration. Besides confirming information on $B_{u…
Multilepton Higgs Decays through the Dark Portal
Chia-Feng Chang, Ernest Ma, Tzu-Chiang Yuan
The U(1)_D gauge sector containing one dark Higgs boson h_D and one dark photon γ_D may be explored through the decays of the 126 GeV particle discovered at the Large Hadron Collid…
