TL;DR
This paper analyzes the expected event rates for direct WIMP dark matter detection, highlighting how modulation signals can reveal the mass of dark matter particles, especially for light WIMPs.
Contribution
It provides detailed calculations of differential event rates and modulation effects for light WIMPs, offering a method to infer dark matter mass from detection signals.
Findings
Modulation amplitude can change sign depending on WIMP mass.
The analysis focuses on low energy transfers and light dark matter candidates.
Modulation signals can be used to estimate WIMP mass.
Abstract
The differential event rate for direct detection of dark matter, both the time averaged and the modulated one due to the motion of the Earth, are discussed. The calculations focus on relatively light cold dark matter candidates (WIMP) and low energy transfers. It is shown that for some WIMP masses the modulation amplitude may change sign. This effect can be exploited to yield information about the mass of the dark matter candidate.
