Description
The measurement of resonances provides a tool to study the hadronic phase, the phase between chemical and kinematic freeze-out in the evolution of the quark-gluon plasma (QGP). Baryonic resonances, such as $\Xi(1530)^0$ with relatively long lifetime ($\sim$ 22 fm/c), serve as key probes to investigate the rescattering and regeneration effects inside the hadron resonance gas by comparing to the short-lived resonances and various models across collision systems. In particular, the study of $\Xi(1530)^0$ (S=-2) can provide insights into the evolution of strangeness. This presentation will discuss the results of $\Xi(1530)^0$ production in pp collisions at 13 and 13.6 TeV measured by ALICE at the LHC. These measurements will serve as a benchmark for future $\Xi(1530)^0$ measurements in larger collision systems.
