Comparison of DAMA/LIBRA and DM ICE Results using Information Theory to Rule out Dark Matter Claims

TL;DR

This paper compares DAMA/LIBRA and DM Ice experimental results using Information Theory, providing evidence that DAMA/LIBRA's data does not support the detection of Dark Matter WIMPs.

Contribution

It introduces an Information Theory-based method to analyze and compare dark matter detection experiments, strengthening the case against DAMA/LIBRA's dark matter claims.

Findings

DAMA/LIBRA's 40K peak suggests no dark matter signal.

DM Ice data supports the absence of WIMPs.

Information Theory analysis reinforces non-detection conclusions.

Abstract

We study the details of the DAMA/LIBRA results and compare those with the recent published DM Ice results of ICE Cube. In various recent papers, it was shown that the 40K peak on DAMA/LIBRA data leaves no room for a Dark Matter signal in the bulk of the data. Using Information Theory for the different types of detection environments, we show that annual variation calculations and the DM Ice data reinforce the claims that the DAMA/LIBRA detector is not observing Dark Matter WIMPs.
