Neutrino-Antineutrino Identification in a Liquid Scintillator Detector: Towards a Novel Decay-at-Rest-based Neutrino CPV Framework

Abstract

We introduce a novel approach to investigate CP violation in the neutrino sector, based on the simultaneous detection of $ν_e$ and $\barν_e$ stemming from the oscillation of $ν_μ$ and $\barν_μ$ produced in the decay at rest of $π$s and $μ$s at a beam dump. This approach relies on a novel liquid scintillator detector technology expected to yield unprecedented identification of $ν_e$ and $\barν_e$ charged-current interactions, which we investigate by means of Montecarlo simulations. Here we report preliminary results concerning both the detection technique and its physics reach.
