More on molecular excitations: Dark matter detection in ice
Jerry Va'vra
TL;DR
This paper explores the potential of detecting dark matter particles, specifically WIMPs, through multi-photon signals generated by molecular vibrations in ice, proposing observational strategies for IceCube.
Contribution
It introduces a novel method of dark matter detection via molecular excitations in ice and suggests observational strategies for IceCube to identify WIMP interactions.
Findings
Multi-photon signals could indicate WIMP interactions in ice.
Yearly modulation of event rates may serve as a signature of dark matter.
Proposes IceCube as a detector for such multi-photon events.
Abstract
In this paper we investigate di-atomic molecules embedded in ice crystals under strain. In this environment coherent vibrations of many OH-bonds may be generated by one WIMP collision. The detection of such multiple-photon signals may provide a signature of a 100~GeV/c WIMP. To do a proper lab test of WIMP-induced multi-photon emission is very difficult. We suggest that Ice Cube make a search for multi-photon events, and investigate whether the rate of such events exhibits yearly modulation.
