Abstract

The production of the strange and double-strange baryon resonances (\(\Sigma (1385)^{\pm }\), \(\Xi (1530)^{0}\)) has been measured at mid-rapidity (\(\left| y \right| \)\(<0.5\)) in proton–proton collisions at \(\sqrt{s}\) \(=\) 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 \(\phi (1860)\) pentaquark, decaying in the \(\Xi \pi \) channel, has been carried out but no evidence is seen.
