(Left) Invariant mass of \Lambdac candidates using standard (cut-based) and BDT selection techniques in Pb--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV for an example \pt interval . The upper panel shows the actual counts and the lower panel the residuals after polynomial background subtraction for the two distributions. (Right) $\delta p_{\text{T}}$ distribution for charged jets with $R = 0.4$ in Pb--Pb collisions at 5.02 TeV. Comparison of ML-based and area-based correction.
