Current Status of Inert Higgs Dark Matter with Dark Fermions
Yi-Zhong Fan, Yao-Yu Li, Chih-Ting Lu +4
The precision measurements of the muon magnetic moment and the boson mass have sparked interest in the potential deviations from standard model (SM) predictions. While it may b…
Searching Accretion-Enhanced Dark Matter Annihilation Signals in the Galactic Centre
MeiWen Yang, Zhi-Qi Guo, Xiao-Yi Luo +5
This study reanalyzes the detection prospects of dark matter (DM) annihilation signals in the Galactic Center, focusing on velocity-dependent dynamics within a spike density near t…
Relic density and temperature evolution of a light dark sector
Xin-Chen Duan, Raymundo Ramos, Yue-Lin Sming Tsai
We have developed a set of four fully coupled Boltzmann equations to precisely determine the relic density and temperature of dark matter by including three distinct sectors: dark…
Weak Lensing Constraints on Dark Matter-Baryon Interactions with -Body Simulations and Machine Learning
Chi Zhang, Lei Zu, Hou-Zun Chen +2
We investigate the elastic scattering cross section between dark matter and protons using the DES Year 3 weak lensing data. This scattering induces a dark acoustic oscillation stru…
Mirror QCD phase transition as the origin of the nanohertz Stochastic Gravitational-Wave Background
Lei Zu, Chi Zhang, Yao-Yu Li +3
Several Pulsar Timing Array (PTA) collaborations have recently provided strong evidence for a nHz Stochastic Gravitational-Wave Background (SGWB). Here we investigate the implicati…
Inelastic Scattering of Dark Matter with Heavy Cosmic Rays
Keyu Lu, Yue-Lin Sming Tsai, Qiang Yuan +1
We investigate the impact of inelastic collisions between dark matter (DM) and heavy cosmic ray (CR) nuclei on CR propagation. We approximate the fragmentation cross-sections for D…
