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.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.93150.v1/t1","@type":"Dataset","description":"$p_{\\rm T}$-distributions of $\\rm{K}^{*0}$ (average of particle and anti-particle)
