nvariant mass distribution of the combination of three prongs, forming the most displaced secondary vertex in jets with 20 < preco T,ch jet < 30 GeV/c, tagged with the default selection SLxy > 7 and σSV < 0.03 cm for pp (left) and p–Pb (right) collisions. The data (black points) are fitted with detector-level MC templates corresponding to beauty, charm, and light-flavor jets to assess the purity of the b-jet candidate sample.
