Hadronic resonances, having very short lifetimes, like , can act as useful probes to understand and estimate the lifetimes of hadronic phases in ultrarelativistic proton-proton, -Pb, and heavy-ion collisions. Resonances with relatively longer lifetime, like mesons, can serve as tools to locate the quark-gluon plasma (QGP) phase boundary. We estimate a lower limit of hadronic phase lifetime in Cu-Cu and Au-Au collisions at the Relativistic Heavy Ion Collider (RHIC) and in -Pb, and Pb-Pb collisions at different Large Hadron Collider (LHC) collision energies. Also, we obtain the effective temperature of mesons using the Boltzmann-Gibbs blast-wave function, which gives insight into locating the QGP phase boundary. We observe that the hadronic phase lifetime strongly depends on final-state charged-particle multiplicity, whereas the QGP phase and hence the QCD phase boundary shows very weak multiplicity dependence. This suggests that the hadronization from a QGP state starts at a similar temperature irrespective of charged-particle multiplicity, collision system, and collision energy, while the endurance of hadronic phase is strongly dependent on final-state charged-particle multiplicity, system size, and collision energy.
