(Left) Hadronic phase duration (time span between chemical and kinetic freeze-out) as a function of $\langle$\dNchdeta$\rangle^{1/3}$ calculated from the $\rho/\pi$, K$^*/$K and $\Lambda^*/\Lambda$ ratios in \PbPb\ collisions at \sqrtSnn{} = 2.76 \tev . The $\rho/\pi$ results are shifted horizontally by 0.1 units for visibility. (Right) Pion–kaon emission asymmetry for \PbPb\ collisions at \sqrtSnn{} = 2.76 \tev\ as a function of $\langle$\dNchdeta$\rangle^{1/3}$ . The shaded areas show predictions from the THERMINATOR 2 model with default and selected values of additional delay $\Delta\tau$ for kaons .
