Displaced Signals from Long-lived Particles in Neutrinoless Double Beta Decay
Patrick D. Bolton, Noor-Inès Boudjema, Frank F. Deppisch +2
Much of the literature on neutrinoless double beta () decay with light new-physics mediators focuses on invisible missing energy. We investigate the scenario in which a massi…
Photon--Dark Matter Elastic Scattering: An Effective-Operator Scan and First Operator-Resolved Sensitivity Estimates from the Galactic Halo
Trinity Rosebud Stenhouse, Asli Acar, Mikhail Bashkanov +3
Elastic photon--dark matter scattering attenuates gamma-ray spectra along a line of sight, probing the same operators as dark matter annihilation to photons but at a rate linear, r…
The 20 GeV Galactic Halo Excess: Pixel-Level Confirmation and Consistency with Sub-TeV WIMP Annihilation
Trinity Rosebud Stenhouse, Chamkaur Ghag, Frank F. Deppisch
A recent analysis of 15 years of Fermi-LAT data reported a spherically symmetric, halo-like component of the Galactic diffuse emission that peaks near 20GeV. We independently repro…
Probing Quasi-Dirac Neutrino Oscillations at Long Baseline Experiments
Noor-Ines Boudjema, Frank F. Deppisch, Suka Sriyansu Pattanaik
The Dirac or Majorana nature of neutrinos remains one of the most fundamental open problems in particle physics. A natural intermediate scenario arises when small lepton-number-vio…
Linking the Gauge Hierarchy with Neutrino Masses and Dark Matter via Two-step Cosmological Selection
Jin-Lei Yang, Frank F. Deppisch
The hierarchy problem between the electroweak (EW) and Planck scales remains a central puzzle in modern physics. We discuss a promising solution operating through the cosmological…
