Scalar and Fermion Two-component SIMP Dark Matter with an Accidental Symmetry
Shu-Yu Ho, Pyungwon Ko, Chih-Ting Lu
In this paper, we construct for the first time a two-component strongly interacting massive particles (SIMP) dark matter (DM) model, where a complex scalar and a vector-like fermio…
Comment on "New Freezeout Mechanism for Strongly Interacting Dark Matter"
Shu-Yu Ho, Chih-Ting Lu
Inspired by our recent paper "reshuffled SIMP dark matter", we notice that the reaction rate of the two-loop induced process may dominate over or be comparable with that…
Explaining the MiniBooNE Anomalous Excess via Leptophilic ALP-Sterile Neutrino Coupling
Chia-Hung Vincent Chang, Chuan-Ren Chen, Shu-Yu Ho +1
Recently, the MiniBooNE experiment at Fermilab has updated the results with increased data and reported an excess of electronlike events () in the neutrino…
Hidden Monopole Dark Matter via Axion Portal and its Implications for Direct Detection Searches, Beam-Dump Experiments, and the Tension
Ryuji Daido, Shu-Yu Ho, Fuminobu Takahashi
Hidden monopole is a plausible dark matter candidate due to its stability, but its direct experimental search is extremely difficult due to feeble interactions with the standard mo…
Relaxing the Cosmological Moduli Problem by Low-scale Inflation
Shu-Yu Ho, Fuminobu Takahashi, Wen Yin
We show that the cosmological abundance of string axions is much smaller than naive estimates if the Hubble scale of inflation, , is sufficiently low (but can still be…
Enhanced photon coupling of ALP dark matter adiabatically converted from the QCD axion
Shu-Yu Ho, Ken'ichi Saikawa, Fuminobu Takahashi
We revisit the adiabatic conversion between the QCD axion and axion-like particle (ALP) at level crossing, which can occur in the early universe as a result of the existence of a h…
