Neutrino-antineutrino identification in a liquid scintillator detector: Towards a novel decay-at-rest-based neutrino CPV framework

We introduce a novel approach to investigate CP violation in the neutrino sector, based on the simultaneous detection of νe and ν̄e stemming from the oscillation of νμ and ν̄μ produced in the decay at rest of πs and μs at a beam target. This approach relies on a novel liquid scintillator detector technology expected to yield unprecedented identification of νe and ν̄e charged-current interactions, which we investigate by means of Monte Carlo simulations. Here we report preliminary results concerning both the detection technique and its physics reach.
