    Abstract:
    The ω̄/ω ≡ ω+/ω- ratio in elementary proton-proton collisions in an unambiguous and sensitive probe for distinguishing particle production through the breakup of a color flux tube from statistical hadronization was presented. Results showed that the antiomega dominance increased with the decrasing beam energy. The behavior was caused by the combinatorics of quark-antiquark production in small and low-mass strings.
