Description
The first measurement of the $\Lambda$(1520) baryonic resonance in pp collisions at $\sqrt{s}=13~$TeV, performed using the ALICE detector at the LHC, is presented. The analysis details for invariant mass reconstruction in the hadronic decay channel $\Lambda$(1520) $\rightarrow$ pK$^{-}$ are discussed. The invariant mass distributions for various $p_{\rm T}$ intervals are obtained from 0 < $p_{\rm T}$ (GeV/$c$) < 6. The invariant $p_{\rm T}$ spectra, integrated yield, $\Lambda$(1520) /$\Lambda$(1115) and mean $p_{\rm T}$ for inelastic collisions are also shown. This measurement serves as a baseline study for measurements performed in Pb-Pb collisions, where modifications to the $\Lambda$(1520) yields may provide insight into the hadronic stage of system evolution.
