description The primary goal of the relativistic heavy-ion physics program at Large Hadron Collider (LHC) at CERN, Geneva, Switzerland is to study the nuclear matter under extreme conditions. The measurement of resonances in ultra-relativistic heavy-ion collisions allows one to study the properties of the hadronic medium. Resonances with short lifetimes compared to the duration of the time span between chemical and kinetic freeze-out are good candidates to prove the interplay of particle re-scattering and regeneration in the hadronic phase, which result in a modification of their measured yields. The ALICE detector and its subsystem used for the analysis presented in this thesis are explained. Particle identification method and a coordinate system of ALICE are provided. Measurements of multi-strange resonance $\Xi(1530)^{0}$ were performed with the ALICE detector in pp, p-Pb and Pb-Pb collisions at the LHC energies. The ${p_{\mathrm{T}}}$-spectra of $\Xi(1530)^{0}$ are obtained and compared with model predictions. The yield ratios of $\Xi(1530)^{0}$ to stable hadrons are shown and discussed. Mean transverse momentum of $\Xi(1530)^{0}$ has been investigated and compared with that of identified hadrons. The comparison of results obtained for other resonances is also presented in this thesis.
