Description

The HIBEAM/NNBAR programme at the European Spallation Source will search for neutrons converting to antineutrons. An important observable is the reconstructed vertex arising from charged particles produced by an antineutron annihilating on a thin target foil and which pass through a time projection chamber. We present a comparison of four methods for vertex coordinate reconstruction: two machine learning (ML)-based methods and two non-ML methods, where one of each is tailored for this study.
