Atomic ionization by sterile-to-active neutrino conversion and constraints on dark matter sterile neutrinos with germanium detectors
Jiunn-Wei Chen, Hsin-Chang Chi, Shin-Ted Lin +5
The transition magnetic moment of a sterile-to-active neutrino conversion gives rise to not only radiative decay of a sterile neutrino, but also its non-standard interaction (NSI)…
Electronic and nuclear contributions in sub-GeV dark matter scattering: A case study with hydrogen
Jiunn-Wei Chen, Hsin-Chang Chi, C. -P. Liu +2
Scattering of sub-GeV dark matter (DM) particles with hydrogen atoms is studied in this paper. The interactions of DM with electrons and nucleons are both included and formulated i…
Constraining neutrino electromagnetic properties by germanium detectors
Jiunn-Wei Chen, Hsin-Chang Chi, Keh-Ning Huang +6
The electromagnetic properties of neutrinos, which are either trivial or negligible in the context of the Standard Model, can probe new physics and have significant implications in…
Constraints on millicharged neutrinos via analysis of data from atomic ionizations with germanium detectors at sub-keV sensitivities
Jiunn-Wei Chen, Hsin-Chang Chi, Hau-Bin Li +5
With the advent of detectors with sub-keV sensitivities, atomic ionization has been identified as a promising avenue to probe possible neutrino electromagnetic properties. The inte…
Atomic ionization of germanium due to neutrino magnetic moments
Jiunn-Wei Chen, Hsin-Chang Chi, Keh-Ning Huang +6
An ab initio calculation of atomic ionization of germanium (Ge) by neutrinos was carried out in the framework of multiconfiguration relativistic random phase approximation. The mai…
Ionization of hydrogen by neutrino magnetic moment, relativistic muon, and WIMP
Jiunn-Wei Chen, C. -P. Liu, Chien-Fu Liu +1
We studied the ionization of hydrogen by scattering of neutrino magnetic moment, relativistic muon, and weakly-interacting massive particle with a QED-like interaction. Analytic re…
