| Abstract | The measurement of the $\Lambda(1520)$ (mass = 1520 MeV/$c^{2}$) resonance production at midrapidity $(|y| < 0.5 )$ in pp collisions at $\sqrt{s}$ = 5.02 and 13 TeV as a function of charged-particle multiplicity is presented. The hadronic decay channel $\Lambda(1520) \rightarrow pK^{-} (\overline{ \Lambda}( 1520)\rightarrow \overline{p}K^{+} $) with branching ratio BR = 22.5 $\pm$ 0.5\% is used to reconstruct $\Lambda(1520)$. It has a lifetime of around 13 fm/$\it{c}$, which lies between the lifetimes of $K^*$ and $\phi$ resonances. The multiplicity-dependent measurement of the $\Lambda(1520)/\Lambda$ ratio for pp collisions can serve as a baseline for heavy-ion collisions. |
