Description

The measurement of short-lived resonances allows the investigation of the collision dynamics and of the properties of the hot and dense medium created in high-energy collisions. We study the production of the two hadronic resonances Δ++(1232) → pπ+ and Λ(1520) → pK− in pp collisions at √s = 7 TeV with the ALICE apparatus at the LHC as a baseline for heavy-ion collisions. We present the performance of the reconstruction and transverse momentum spectra. The Δ++(1232)/p and Λ(1520)/Λ0 ratios obtained from previous pp collisions and thermal model calculations are also presented.
