Relativistic Impulse Approximation in the Atomic Ionization Process induced by Millicharged Particles
Chen-Kai Qiao, Shin-Ted Lin, Hsin-Chang Chi +1
The millicharged particle has become an attractive topic to probe physics beyond the Standard Model. In direct detection experiments, the parameter space of millicharged particles…
Model-independent determination of the Migdal effect via photoabsorption
C. -P. Liu, Chih-Pan Wu, Hsin-Chang Chi +1
The Migdal effect in a dark-matter-nucleus scattering extends the direct search experiments to the sub-GeV mass region through electron ionization with sub-keV detection thresholds…
Compton Scattering Energy Spectrum for Si and Ge Systems
Chen-Kai Qiao, Hsin-Chang Chi, Shin-Ted Lin +3
In the present work, we study the atomic Compton Scattering which could have great impacts on dark matter direct detection experiments. We give a quantitative analysis of the Compt…
Discovery potential of multi-ton xenon detectors in neutrino electromagnetic properties
Chung-Chun Hsieh, Lakhwinder Singh, Chih-Pan Wu +5
Next-generation xenon detectors with multi-ton-year exposure are powerful direct probes of dark matter candidates, in particular the favorite weakly-interacting massive particles.…
Relativistic Impulse Approximation in Compton Scattering
Chen-Kai Qiao, Hsin-Chang Chi, Lei Zhang +5
Relativistic impulse approximation (RIA) has been widely used in atomic, condensed matter, nuclear, and elementary particle physics. In former treatments of RIA formulation, differ…
Relativistic photoionization of H isoelectronic series including plasma shielding effects
Xugen Zheng, Hsin-Chang Chi, Shin-Ted Lin +3
With plasma shielding effects of the Debye-Hückel model, we investigate the relativistic photoionization processes of H, Nb and Pb plasmas in the H-isoelectronic se…
