On the Cosmic Ray Muon Hypothesis for DAMA
Josef Pradler
TL;DR
This paper critically examines the hypothesis that cosmic ray muons cause the annual modulation observed by DAMA, providing arguments and new comments to challenge this explanation.
Contribution
It offers a detailed critique of the cosmic ray muon hypothesis and adds new insights to the ongoing debate about the DAMA modulation origin.
Findings
Cosmic ray muons are unlikely to cause DAMA's observed modulation.
Arguments challenge the correlation between muon flux and DAMA signal.
Provides new comments on recent related research.
Abstract
The DAMA dark matter search experiment observes a statistically significant percent-level variation of its low-energy count rate with a period of one year. In this note we recall some of the arguments which challenge the hypothesis that the cosmic ray induced underground muon flux can be the origin of the modulation. In addition, we provide new comments on recent works on this subject.
