Invariant mass distribution for ${\rm K_S^0}$, $\Lambda$, $\Xi^-$, and $\Omega^-$ in different $\pT$ intervals in MB p-Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV. The candidates are reconstructed in $|\eta|<0.75$. The grey areas are used to determine the background (red dashed lines), see text for details.
