Top: invariant mass distributions of D0-jet candidates for 2 < pT,ch jet < 50 GeV/c and R = 0.4 in pp collisions at √s = 5.02 TeV, in the D0-meson transverse momentum intervals: 3 < pT,D0 < 4 GeV/c (left), 7 < pT,D0 < 8 GeV/c (centre), and 10 < pT,D0 < 12 GeV/c (right). The total fit function is represented by the blue solid line, while the red dashed line represents the sum of the background and reflection fit functions. The red and green shaded areas correspond to the peak and sideband regions, respectively. Bottom: D0-jet raw yields as a function of pT,ch jet in the signal and sideband regions, and their subtracted yields.
