Neutrinoless Double Beta Decay Searches With The Xenon Dark Matter Experiment

, 2018
The XENON1T experiment is leading the sensitivity to spin-independent, elastic WIMP-nucleon scatters, excluding cross-sections down to 7.7·10−47 ^{−47} cm2 ^2 at a mass of 35 GeV/c2 ^2 (90% CL) with the first science run of 34 days. A second science run with 247 live days is currently under analysis.

Minimal scoto-seesaw mechanism with spontaneous CP violation

Journal of High Energy Physics, 2021
We propose simple scoto-seesaw models to account for dark matter and neutrino masses with spontaneous CP violation. This is achieved with a single horizontal Z 8 $$ {\mathcal{Z}}_8 $$ discrete symmetry, broken to a residual Z 2 $$ {\mathcal{Z}}_2 ...

Migdal effect in dark matter direct detection experiments

Journal of High Energy Physics, 2018
The elastic scattering of an atomic nucleus plays a central role in dark matter direct detection experiments. In those experiments, it is usually assumed that the atomic electrons around the nucleus of the target material immediately follow the motion of
