Jovian signal at BOREXINO

Abstract

The BOREXINO experiment has been collecting solar neutrino data since 2007, providing the opportunity to study the variation of the event rate over a decade. We find that at 96% C.L., the rate of low energy events shows a time modulation favoring a correlation with a flux from Jupiter. We present a new physics model, the Jovian whisper model, based on dark matter of mass ∼0.1–4  GeV captured by Jupiter that can account for such modulation. We discuss how the Jovian whisper model (JWM) can be tested. Published by the American Physical Society 2024
