$\lambda$ parameters ($\lambda_{\rm {p}\rm {p}}+\lambda_{\rm {p}\Lambda}$ in case of (anti)proton pairs) vs. $m_{\rm T}$ for the three centralities considered for $\pi^{\pm}\pi^{\pm}$, $\rm K^{\pm}\rm K^{\pm}$,$\Kzs\Kzs$, $\rm {p}\rm {p}$, and $\overline{\rm p}\overline{\rm p}$. Statistical (thin lines) and systematic (boxes) uncertainties are shown. The $m_{\rm T}$ values for different centrality intervals are slightlyoffset for clarity.
