Query: Evidence of rescattering effect in Pb-Pb collisions at the LHC through
  production of $\rm{K}^{*}(892)^{0}$ and $\phi(1020)$ mesons   Measurements of $\rm{K}^{*}(892)^{0}$ and $\phi(1020)$ resonance production
in Pb-Pb and pp collisions at $\sqrt{s_{\rm{NN}}}$ = 5.02 TeV with the ALICE
detector at the Large Hadron Collider are reported. The resonances are measured
at midrapidity ($|y|$ $<$ 0.5) via their hadronic decay channels and the
transverse momentum ($p_{\rm{T}}$) distributions are obtained for various
collision centrality classes up to $p_{\rm{T}}$ $=$ 20 GeV$/c$. The
$p_{\rm{T}}$-integrated yield ratio $\rm{K}^{*}(892)^{0}$$/$K in Pb-Pb
collisions shows significant suppression relative to pp collisions and
decreases towards more central collisions. In contrast, the $\phi(1020)$$/$K
ratio does not show any suppression. Furthermore, the measured
$\rm{K}^{*}(892)^{0}$$/$K ratio in central Pb-Pb collisions is significantly
suppressed with respect to the expectations based on a thermal model
calculation, while the $\phi(1020)$$/$K ratio agrees with the model prediction.
These measurements are an experimental demonstration of rescattering of
$\rm{K}^{*}(892)^{0}$ decay products in the hadronic phase of the collisions.
The $\rm{K}^{*}(892)^{0}$$/$K yield ratios in Pb-Pb and pp collisions are used
to estimate the time duration between chemical and kinetic freeze-out, which is
found to be $\sim$ 4-7 fm$/c$ for central collisions. The
$p_{\rm{T}}$-differential ratios of $\rm{K}^{*}(892)^{0}$$/$K,
$\phi(1020)$$/$K, $\rm{K}^{*}(892)^{0}$$/\pi$, $\phi(1020)$$/\pi$,
$p/$$\rm{K}^{*}(892)^{0}$ and $p/$$\phi(1020)$ are also presented for Pb-Pb and
pp collisions at $\sqrt{s_{\rm{NN}}}$ $=$ 5.02 TeV. These ratios show that the
rescattering effect is predominantly a low-$p_{\rm{T}}$ phenomenon.
