Direct detection of light dark matter and solar neutrinos via color center production in crystals

Physics Letters B, 2018
We propose a new low-threshold direct-detection concept for dark matter and for coherent nuclear scattering of solar neutrinos, based on the dissociation of atoms and subsequent creation of color center type defects within a lattice.

Dark radiation and superheavy dark matter from black hole domination

Journal of High Energy Physics, 2019
If even a relatively small number of black holes were created in the early universe, they will constitute an increasingly large fraction of the total energy density as space expands.

Dark Energy Constraints from Galaxy Cluster Peculiar Velocities

, 2008
Future multifrequency microwave background experiments with arcminute resolution and micro-Kelvin temperature sensitivity will be able to detect the kinetic Sunyaev-Zeldovich (kSZ) effect, providing a way to measure radial peculiar velocities of massive ...

Non-relativistic effective theory of dark matter direct detection

, 2010
Dark matter direct detection searches for signals coming from dark matter scattering against nuclei at a very low recoil energy scale ~ 10 keV. In this paper, a simple non-relativistic effective theory is constructed to describe interactions between dark

A cosmic window on the dark axion portal

Journal of High Energy Physics
Axions and dark photons are common in many extensions of the Standard Model. The dark axion portal — an axion coupling to the dark photon and photon — can significantly modify their phenomenology.

Experiments on bright-field and dark-field high-energy electron imaging with thick target material

Physical Review Accelerators and Beams, 2018
High-energy charged particle radiography has been used for diagnostics of high-energy density matter, and electrons can serve as a promising radiographic probe that acts as a complement to commonly used proton probes.

Earth-scattering induced modulation in low-threshold dark matter experiments

Journal of High Energy Physics
Dark matter particles with sufficiently large interactions with ordinary matter can scatter in the Earth before reaching and scattering in a detector. This induces a modulation in the signal rate with a period of one sidereal day.
