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.
