Constraints on millicharged particles with low threshold germanium detectors at Kuo-Sheng Reactor Neutrino Laboratory
read the original abstract
Relativistic millicharged particles ($\chi_q$) have been proposed in various extensions to the Standard Model of particle physics. We consider the scenarios where they are produced at nuclear reactor core and via interactions of cosmic-rays with the earth's atmosphere. Millicharged particles could also be candidates for dark matter, and become relativistic through acceleration by supernova explosion shock waves. The atomic ionization cross section of $\chi_q$ with matter are derived with the equivalent photon approximation. Smoking-gun signatures with significant enhancement in the differential cross section are identified. New limits on the mass and charge of $\chi_q$ are derived, using data taken with a point-contact germanium detector with 500g mass functioning at an energy threshold of 300~eV at the Kuo-Sheng Reactor Neutrino Laboratory.

Searches for CE{\nu}NS and Physics beyond the Standard Model using Skipper-CCDs at CONNIE
CONNIE's first Skipper-CCD run at Angra-2 yields no CEνNS excess, comparable prior limits on neutrino rates, improved bounds on light vector mediators, and record surface DM-electron limits via diurnal modulation.

Migdal Ionization as a Probe of Light Dark Matter from Nuclear Transition
Migdal ionization of reactor-produced sub-MeV dark matter in TEXONO germanium yields new 95% C.L. limits on the reference DM–proton cross section for 0.01 MeV ≤ mχ ≲ 2.6 MeV.

Migdal Ionization as a Probe of Light Dark Matter from Nuclear Transition
Migdal ionization in a germanium detector can turn reactor-produced sub-MeV dark matter into observable signals, yielding new 95% C.L. limits on the DM–proton cross section for masses 0.01–2.6 MeV.

Constraints on Axion-Like Particles with the Silicon Detector at a Nuclear Reactor
New 90% C.L. limits on the ALP–photon coupling in the 0.1–100 keV range are derived from Connie and Atucha-II reactor data via plasmon excitation in silicon; a 30 kg·yr Oscura-style run could improve on NEON by about tenfold.
