Analyzing Direct Dark Matter Detection Data by the AMIDAS Website

TL;DR

This paper presents a method for analyzing direct dark matter detection data using the AMIDAS website, successfully reconstructing WIMP properties with reasonable accuracy without prior astrophysical assumptions.

Contribution

It introduces a data analysis approach that accurately extracts WIMP properties from pseudodata without relying on standard astrophysical models.

Findings

WIMP mass and couplings can be reconstructed with 5-40% deviation.

The method works with non-standard astrophysical setups.

No prior knowledge of local dark matter distribution is required.

Abstract

In this talk I have presented the data analysis results of extracting properties of halo WIMPs: the mass and the (ratios between the) spin-independent and spin-dependent couplings/cross sections on nucleons by the AMIDAS website. Although non-standard astronomical setup has been used to generate pseudodata sets for our analyses, it has been found that, without prior information/assumption about the local density and velocity distribution of halo Dark Matter, these WIMP properties have been reconstructed with ~5% to < ~40% deviations from the input values.
