TL;DR
This paper investigates how boron solar neutrinos can create background noise in future direct dark matter detection experiments, potentially affecting sensitivity to very rare events.
Contribution
It analyzes the coherent scattering of solar neutrinos as a background source, highlighting its significance for next-generation dark matter searches.
Findings
Solar neutrinos can produce background signals in dark matter detectors.
Neutrino coherent scattering may limit future dark matter detection sensitivity.
Boron solar neutrinos are a notable background in low-threshold experiments.
Abstract
The coherent contribution of all neutrons in neutrino nucleus scattering due to the neutral current is examined considering the boron solar neutrinos. These neutrinos could potentially become a source of background in the future dark matter searches aiming at nucleon cross sections in the region well below the few events per ton per year.
