In this study, the decay Ω0c → Ξ−K−π+π+ is analysed to search for the presence of excited Ω− baryon states. 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 Ω0c
mass peak, enabling the exploration of
excited states. The invariant mass spectra reveal hints of a potential resonance
