Using data from the LHCb experiment, a Boosted Decision Tree (BDT) classifier is developed, enhancing the signal-to-background ratio by a factor 2 compared to standard selection criteria. This approach resulted in a clean $\Omega_c^0$ mass peak, enabling the exploration of excited states. The invariant mass spectra reveal hints of a potential resonance.</ab> <la>eng</la> <k1/> <pb/> <pp/> <yr>2024</yr> <ed/> <ul>http://cds.cern.ch/record/2921782/files/CERN-THESIS-2024-308.pdf; </ul> <no>Imported from Invenio.</no> </reference> </references>
