Higgsino Dark Matter Interpretation of the LUX-ZEPLIN 248 keV Nuclear-Recoil Event
Katherine Freese, Dionysios P. Theodosopoulos
We propose Higgsino dark matter as a potential interpretation of the nuclear-recoil event of interest reported by the LUX-ZEPLIN (LZ) experiment. LZ studied seve…
Paleo-Detectors as a Novel Probe of Dark Matter-Nucleus Effective Interactions
Dionysios P. Theodosopoulos
Paleo-detectors are a proposed approach to the direct detection of dark matter (DM) based on the observation of DM-induced nuclear recoils. Rather than relying on large detector ma…
Reconstructing Dark Matter Mass and Discriminating Standard and Non-Standard WIMP-Nucleus Interactions with Paleo-Detectors
Dionysios P. Theodosopoulos, Katherine Freese, Chris Kelso +1
Paleo-detectors record and retain crystal damage in ancient minerals from nuclear recoils induced by dark matter scattering over geological timescales. Previous studies have shown…
Self-Gravitating Magnetic Monopoles and Dyons in String-Inspired Models: Structure and Stability
Nick E. Mavromatos, Sarben Sarkar, Dionysios P. Theodosopoulos
We present classical magnetic--monopole (MM) and dyon solutions induced by global monopoles in string-inspired gravitational models. Although several ingredients of the constructio…
Projected Sensitivity of Paleo-Detectors to Dark Matter Effective Interactions with Nuclei
Dionysios P. Theodosopoulos, Katherine Freese, Chris Kelso +1
Paleo-detectors are a proposed experimental technique for direct detection (DD) of dark matter (DM) via the read-out of DM-induced nuclear recoil tracks in natural minerals. The la…
