Left: Invariant-mass distribution of \Dzero-jet candidates for \jetptrange{10}{20}, with \Dzero-meson candidates in \ptDrange{8}{12} and $R=0.4$ The total fit function is depicted by the dashed blue line, while the solid red line represents the background fit function. The blue and green shaded areas correspond to the signal and sideband regions, respectively. Right: The distribution of the raw \Dzero-tagged jet yields as a function of jet angularity $\lambda_{\alpha=1}$ in the signal (blue) and sideband (green) regions, along with the background-subtracted (red) yields.
