    "abstract": "The recombination model is applied to the production of phi and Omega at all\npt in central Au+Au collisions. Since no light quarks are involved in the\nhadronization, those hidden-strange particles present a clean slate for the\nstudy of the role of strange quarks in large-pt physics. We find that shower s\nquarks have negligible effect for pt\u003c6 GeV/c, in which range the thermal s\nquarks make the dominant contributions to the formation of phi and Omega. We\nshow that the same effective temperature of the s quarks is responsible for the\nshape of the spectra of both phi and Omega. We predict that the ratio of Omega\nto phi will show a peak at pt \\approx 6 GeV/c due to the effect of the hard\npartons. We also give reasons on the basis of the pt dependence that phi cannot\nbe formed by means of K+K- coalescence.",
