The production of the strange and double-strange baryon resonances ( Σ(1385)± , Ξ(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.

Abstract
The production of the strange and double-strange baryon resonances ( Σ(1385)± , Ξ(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 Ξπ channel, has been carried out but no evidence is seen.File in questo prodotto:
