报告摘要

　　In this talk, I will present my research on short-lived hadronic resonances as sensitive probes of the strongly interacting matter created in high-energy collisions. I will begin with an overview of my PhD work with the ALICE experiment at the LHC, where I investigated the event-shape dependence of charged K*(892) meson production in proton–proton collisions. This study offers valuable insights into hadronization dynamics and collective-like effects in small systems. I will then discuss my current postdoctoral research at IJCLab, where I work within the HADES collaboration at GSI, focusing on φ-meson production in proton–proton collisions. I will highlight the analysis strategies, challenges in background subtraction, and the implications for strangeness production and in-medium modifications. The talk will also briefly cover my experience in phenomenological studies using Monte Carlo event generators (e.g., PYTHIA 8, AMPT) and machine learning techniques applied to hadron spectroscopy. I will conclude by outlining potential future directions and opportunities for collaboration.
