Description
Resonances are used to study the properties of the strongly interacting hot
and dense matter produced in ultrarelativistic heavy$-$ion collisions. The
system produced in such collisions evolves through different stages from
early partonic phase to the hadronic one. Resonances can probe the existence
of hadron rescattering and regeneration effects after hadronization. These
effects can change resonance yields which are measured through their
hadronic decay channels. We report the measurements of hadronic resonance
production in Pb$-$Pb collisions at $\sqrt{s_{NN}}$ = 2.76 TeV with ALICE
detector at the LHC. Transverse momentum spectra, integrated yields, mean transverse momenta, particle ratios and nuclear modification factors of
$K^{*}(892)^{0}$ and $\phi(1020)$ mesons will be discussed and compared
to the corresponding measurements in other collision systems. The results
will also be compared to theoretical model predictions.
