DOI: 10.1038/s42005-024-01827-y
Abstract: Weakly interacting massive particles (WIMPs) are well-motivated candidates for dark matter. One signature of galactic WIMPs is the annual modulation expected in a detector’s interaction rate, which arises from Earth’s revolution around the Sun. Over… read more here.

DOI: 10.1088/1475-7516/2020/02/007
Abstract: We evaluate the statistical significance of the DAMA/LIBRA claims for annual modulation using three independent model comparison techniques, viz frequentist, information theory, and Bayesian analysis. We fit the data from the DAMA/LIBRA experiment to both… read more here.

DOI: 10.1093/ptep/ptaf160
Abstract: The dark matter observation claimed by the DAMA/LIBRA experiment has been a long-standing puzzle within the particle physics community. NaI(Tl) crystals with radiopurity comparable to DAMA/LIBRA’s are essential for adequate verification. Existing experiments using NaI(Tl)… read more here.

DOI: 10.1103/ntnl-zrn9
Abstract: The nature of dark matter, which constitutes 27% of the Universe's matter-energy content, remains one of the most challenging open questions in physics. Over the past two decades, the DAMA/LIBRA experiment has reported an annual… read more here.

DOI: 10.1103/physrevd.98.123007
Abstract: The current paradigm for dark matter direct detection is to assume that the dark sector is solely composed of a single particle species. In this short paper, we make the observation that dark matter comprising… read more here.

Proton-philic spin-dependent inelastic dark matter as a viable explanation of DAMA/LIBRA-phase2

DOI: 10.1103/physrevd.99.023017
Abstract: We show that the Weakly Interacting Massive Particle scenario of proton-philic spin-dependent inelastic Dark Matter (pSIDM) can still provide a viable explanation of the observed DAMA modulation amplitude in compliance with the constraints from other… read more here.
