Event reconstruction for opaque liquid scintillator detectors. — •Kitzia Hernandez for the NuDoubt collaboration — Johannes Gutenberg-Universität Mainz

Opaque liquid scintillators represent a novel approach to particle detection. This technology uses Mie scattering to confine the scintillation light around its interaction point, conserving the topology of the event in comparison with classical transparent scintillators. However, the opacity of these detectors and their energy deposition topologies represent a new paradigm opening the way to new reconstruction methods.

Here, we explore the adaptation of the Cambridge-Aachen jet clustering algorithm, traditionally used in High-energy physics, for event reconstruction in opaque liquid scintillator detectors. By clustering optical photons in the x-y plane and incorporating timing information, this method can effectively reconstruct event position, energy, and particle type. Furthermore, it provides a robust framework for particle discrimination and is a reference point for comparing with more sophisticated approaches using Graphic Neural Networks.
