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 ${\nu }_e$ and ${\bar{\nu }}_e$ stemming from the oscillation of ${\nu }_{\mu }$ and ${\bar{\nu }}_{\mu }$ produced in the decay at rest of $\pi$s and $\mu$s at a beam dump. This approach relies on a novel liquid scintillator detector technology expected to yield unprecedented identification of ${\nu }_e$ and ${\bar{\nu }}_e$ 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.
