Analysis
This paper is important because it combines data from two different experiments (ANAIS-112 and COSINE-100) to search for evidence of dark matter. The negative result, finding no statistically significant annual modulation signal, helps to constrain the parameter space for dark matter models and provides valuable information for future experiments. The use of Bayesian model comparison is a robust statistical approach.
Key Takeaways
- •Combined data from ANAIS-112 and COSINE-100 was analyzed.
- •No statistically significant annual modulation signal was found.
- •Bayesian model comparison was used.
- •Analysis codes are publicly available.

“The natural log of Bayes factor for the cosine model compared to the constant value model to be less than 1.15... This shows that there is no evidence for cosine signal from dark matter interactions in the combined ANAIS-112/COSINE-100 data.”
