Abstract
The production of the strange and double-strange baryon resonances ((1385)±, (1530)0) has been measured at mid-rapidity (|y|< 0.5) in proton–proton collisions at √s = 7 TeV with the ALICE detector at the LHC. Transverse momentum spectra for inelastic collisions are compared to QCD-inspired models, which in general underpredict the data. A search for the φ(1860) pentaquark, decaying in the π channel, has been carried out but no evidence is seen.
