Constraining Vector Dark Matter with Neutrino Experiments

Event Details

Vector Dark Matter (VDM) that couples to lepton flavor (L_e, L_mu, L_tau) acts similarly to a chemical potential for the neutrino flavor eigenstates and modifies neutrino oscillations.  VDM imparts unique signatures such as time and directional dependence.  We use the non-observation of such a signal at Super-Kamiokande to rule out the existence of VDM in a region of parameter space several orders of magnitude beyond other constraints and show the projected reach of future experiments such as DUNE.
