QCD Axion Dark Matter in String Theory: Haloscopes and Helioscopes as Probes of the Landscape
Naomi Gendler, David J. E. Marsh
Laboratory experiments have the capacity to detect the QCD axion in the next decade, and precisely measure its mass, if it composes the majority of the dark matter. In type IIB str…

Dilatonic Couplings and the Relic Abundance of Ultralight Dark Matter
Ahmad Alachkar, Malcolm Fairbairn, David J. E. Marsh
Models of scalar field dark matter where the scalar is a dilaton have a special behaviour, since non-trivial couplings, , to matter result in a contribution to the potential for…

Dwarf galaxies imply dark matter is heavier than
Tim Zimmermann, James Alvey, David J. E. Marsh +2
It is widely established that a lower bound on the dark matter particle mass, , can be obtained by demanding that the de Broglie wavelength in a given galaxy must be smaller tha…
