Production of Σ(1385)± and Ξ(1530)0 in proton–proton collisions at s= 7 TeV

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.
