$\pT$-differential density, $\dd\rho/\dd\pT$, of $\kzero$ (left panel), $\lmb$ (middle panel) and $\Xi$ (right panel) for the \cent{0}{10} event multiplicity class in \pPb collisions at \fivenn The spectra of JE particles (red inverted-triangle), associated with hard scatterings, are compared with that of JC (green squares) and UE (blue open circles) selections The results from inclusive measurements (black closed circles) are presented as well The statistical uncertainties are represented by the vertical error bars and the systematic uncertainties by the boxes.
