New Windows on Heavy Dark Matter: Mineral Melt Modelling and X-Ray Readout for Muscovite Mica
Yilda Boukhtouchen, Joseph Bramante, Andrew Buchanan +5
Muscovite mica is a translucent, layered silicate mineral whose basal cleavage, low radiogenic background, gigayear exposures, and demonstrated track retention over geological time…
Revisiting Turner Window Axions: The Untapped Potential of NaI Dark Matter Detectors
W. C. Haxton, Xing Liu, Anupam Ray +1
The "Turner window" corresponds to axions with masses 1 eV that have sufficiently strong couplings to matter to evade limits from the cooling of SN1987A. This window, thr…
New physics in multi-lepton tau decays
Yohei Ema, Patrick J. Fox, Matheus Hostert +4
Dark particles with lepton-flavor-violating couplings to the tau lepton can induce rare neutrinoless decays with large final state multiplicities. We study models where transi…
Is the Turner Window Open? Seeking Closure with Resonant Absorption of Galactic Axions in NaI Dark Matter Detectors
W. C. Haxton, Xing Liu, Anupam Ray +1
Motivated by the DAMA/LIBRA annual modulation signal, the dark matter community has invested heavily in ultra-clean underground NaI detectors to search for light WIMPs. We point ou…
Detecting Dark Matter with Neutron Stars
Anupam Ray
Neutron stars offer powerful astrophysical laboratories to probe the properties of dark matter. Gradual accumulation of heavy, non-annihilating dark matter in neutron stars can lea…
Beyond Hawking evaporation of black holes formed by dark matter in compact stars
Ujjwal Basumatary, Nirmal Raj, Anupam Ray
The memory burden effect is an explicit resolution to the information paradox by which an evaporating black hole acquires quantum hair, which then suppresses its rate of mass loss…
