First Results of Tokyo Dark Matter Search with a Lithium Fluoride Bolometer

TL;DR

This paper reports initial findings from Tokyo's dark matter search using a lithium fluoride bolometer, providing new limits on WIMP interactions based on measured background spectra.

Contribution

It presents the first results from a lithium fluoride bolometer in dark matter detection, establishing exclusion limits for spin-dependent WIMP interactions.

Findings

Measured background spectrum in surface lab

Derived exclusion plot for spin-dependent WIMP cross section

First results from Tokyo dark matter search with lithium fluoride bolometer

Abstract

The First results of the Tokyo dark matter search programme using a 21-g lithium fluoride bolometer are presented. The background spectrum was measured in the surface laboratory. We derive an exclusion plot for the spin-dependently coupled Weakly Interacting Massive Particles (WIMPs) cross section.
