Description
In this talk we will present novel ways in which neutrino oscillation experiments can probe dark matter. In
particular, we focus on interactions between neutrinos and ultra-light (“fuzzy”) dark matter particles
with masses of order $10^{-22}$ eV. It has been shown previously that such dark matter candidates are
phenomenologically successful and might help ameliorate the tension between predicted and observed
small scale structures in the Universe. We will show that coherent forward scattering of neutrinos on
fuzzy dark matter particles can significantly alter neutrino oscillation probabilities and lead to the effects which
could be observable in current and future experiments. We present new limits on fuzzy dark matter (both scalar and vector)
interacting with neutrinos using data from long-baseline accelerator experiments as well as the solar neutrino data.
