The study of resonances in √s = 7 TeV pp collisions provides a test of QCD in a new energy domain as well as a baseline for heavy-ion collisions. The resonances K*(892)0, ϕ(1020), Σ(1385)±, Λ(1520), and Ξ(1530)0 have been reconstructed at midrapidity from their hadronic decay using data collected by the ALICE detector. The comparison of ϕ(1020) and Σ(1385) pT-spectra to QCD-inspired models such as PHOJET and different PYTHIA tunes are shown.
