  "abstract": "<p>The Standard Model (SM) successfully describes fundamental particles but fails to explain dark matter (DM). The Belle II experiment searches for new particles like the dark photon <span class=\"math-tex\">\\(A'\\)</span>&nbsp;through electron-positron collisions, for example in the process <span class=\"math-tex\">\\(e^+e^- \\to \\gamma A', A' \\to \\mu^+\\mu^-\\)</span>. This thesis focuses on using the CATHODE method, which trains a classifier on Monte Carlo (MC) simulations to distinguish signal-like anomalies implying dark photons.</p>",
