Harikrishnan Ramani, "Detecting terrestrial dark matter traffic jams"


Subcomponent dark matter having large interactions with the standard model or with itself can accumulate terrestrially over the age of the earth leading to massive build-up (comparable to the USPS). This thermalized population is too cold to be visible in traditional direct detection. In this talk I outline a few detection strategies including accelerating this slow dark matter with metastable nuclear isomers or with electrostatic accelerators like LUNA. Intriguingly such a terrestrial component could explain the neutron bottle-beam anomaly and can cause anomalous heating in cryogenic detectors.
