The Omega Puzzle

Abstract

Recent data on particles associated with Omega trigger suggest that such events have jet structure. However, the exponential pT distribution of Omega suggests that no jets are involved. We resolve this puzzle by suggesting that the Omega is produced by the recombination of the enhanced thermal partons in the ridge that can have other hadrons in association with the trigger, all having exponential pT distributions.
