($\Omega$ + $\overline{\Omega}$)/$\phi$ ratio as a function of transverse momentum for pp collisions at $\sqrt{s}$ = 7 TeV $\Omega$ data are from [12]. The dashed line represents the prediction of HIJING/B$\overline{\rm B}$ v2.0 model with a SCF for pp collisions at $\sqrt{s}$ = 5.5 TeV with a string tension of 2 GeV/fm [13]. The same calculation at 7 TeV yields a $\sim$ 10% higher ratio. The full line represents the prediction of the PYTHIA Perugia 2011 tune [14] for pp collisions at $\sqrt{s}$ = 7 TeV.
