Higgsino dark matter compatible with the LUX-ZEPLIN high-energy nuclear-recoil event and IceCube constraints
Katherine Freese, Dionysios P. Theodosopoulos
We examine Higgsino dark matter (DM) as a potential explanation of the nuclear-recoil event of interest reported by the LUX-ZEPLIN (LZ) experiment, taking into a…
Mineral Detection of Neutrinos and Dark Matter 2026 Proceedings
Alexey Elykov, Patrick Stengel, Natsue Abe +81
The fourth "Mineral Detection of Neutrinos and Dark Matter" (MDvDM'26) meeting was held April 14-17, 2026 in Karlsruhe, Germany, hosted by the Institute for Astroparticle Physics (…
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…
Motion of particles around a magnetically charged Euler-Heisenberg black hole with scalar hair and the Event Horizon Telescope
Dionysios P. Theodosopoulos, Thanasis Karakasis, George Koutsoumbas +1
We study the motion of uncharged particles and photons in the background of a magnetically charged Euler-Heisenberg (EH) black hole (BH) with scalar hair. The spacetime can be asym…
Motion of particles in a magnetically charged Euler-Heisenberg black hole with scalar hair
Thanasis Karakasis, George Koutsoumbas, Eleftherios Papantonopoulos
We study the geodesic motion of uncharged particles in the background of a magnetically charged Euler-Heisenberg black hole with a scalar hair. The spacetime can be asymptotically…
Global Monopoles in the Extended Gauss-Bonnet Gravity
Nikos Chatzifotis, Nick E. Mavromatos, Dionysios P. Theodosopoulos
We discuss self-gravitating global O(3) monopole solutions associated with the spontaneous breaking of O(3) down to a global O(2) in an extended Gauss Bonnet theory of gravity in (…
