Description
Resonances play a crucial role in probing the characteristic of the hadronic phase, created in ultra-relativistic heavy-ion collisions. Rescattering and regeneration processes influence the measurable resonance yields and $p_{\rm T}$ spectra shapes. Measurements of resonance productions in high-multiplicity pp collisions could provide insight into the possible presence of a hadronic phase in small collision systems. The $\Lambda(1520)$ resonance, with a lifetime of approximately 13 fm/$\it{c}$, provides additional insights into the hadronic phase compared to the $\rm K^{*0}$ (4 fm/$\it{c}$) and $\rm \phi$ (46 fm/$\it{c}$) resonances. This contribution presents recent measurement of $\Lambda(1520)$ resonance production in high-multiplicity pp collisions, including $p_{\rm T}$ integrated yield ($\frac{dN}{dy}$), mean transverse-momentum ($\langle p_{T} \rangle$), and particle yield ratios as a function of charged-particle multiplicity.
