Recommended conventions for reporting results from direct dark matter searches

Area of Science:

• * Particle Physics
• * Astrophysics
• * Experimental Physics

Background:

• * Dark matter direct detection experiments face challenges in standardizing analysis and presentation of results.
• * Inconsistent methodologies, particularly in statistical inference, hinder result comparison and combination.
• * Existing recommendations for astrophysical parameters and particle fluxes require updates.

Purpose of the Study:

• * To propose standardized recommendations for presenting dark matter direct detection results.
• * To offer guidance on applying the Profile Likelihood Ratio method to experimental data.
• * To provide updated recommendations for Standard Halo Model astrophysical parameters and neutrino fluxes.

Main Methods:

• * Development of recommendations based on input from major dark matter direct detection collaborations.
• * Focus on statistical inference methods, specifically the Profile Likelihood Ratio.
• * Review and update of Standard Halo Model astrophysical parameters and neutrino flux models.

Main Results:

• * A set of recommendations for presenting dark matter direct detection results, particularly for weak-scale dark matter.
• * Guidance on the application of the Profile Likelihood Ratio method.
• * Updated parameters for Standard Halo Model and relevant neutrino fluxes.

Conclusions:

• * Standardized presentation of dark matter direct detection results will improve comparability and facilitate combination of data.
• * Adoption of these recommendations will streamline analysis and enhance the efficiency of dark matter searches.
• * The proposed guidelines are applicable to various dark matter candidates, including very light dark matter and axions.
