  • Abstract:
  • This paper presents a hybrid quantum-classical framework for classifying CERN CMS Open Data events containing charged leptons and neutrinos. A balanced dataset of 200,000 events was formed by combining 100,000 Wmunu and 100,000 Wenu samples, from which 26 engineered kine- matic and detector-level features were constructed. Classical baselines based on XGBoost, LightGBM, and CatBoost achieved 100.0% accuracy, 100.0% precision, 100.0% recall, 100.0% F1-score, and 1.000 ROC-AUC on the held-out test set. The quantum branch used median imputation, standard- ization, PCA reduction to four components, angle encoding on a 4-qubit circuit, and a PennyLane quantum kernel with an SVM classifier. The best quantum configuration achieved 99.0% accuracy, 98.04% precision, 100.0% recall, 99.01% F1-score, and 1.000 ROC-AUC on a balanced 100-event subset, with 49 true negatives, 1 false positive, 0 false negatives, and 50 true positives. The results confirm that compact quantum-kernel learning is competitive, although classical ensembles remain superior on this highly separable benchmark.
