Abstract
The relative rates of top quark hadronization and decay are investigated for the reaction e +e −→ t t . A simple model is used in which hadronization becomes important when the top quarks are separated from one another by more than a distance Λ −1, of order 1 fm. In this model, hadronization occurs before decay for any center-of-mass energy s which satisfies s⩾4m t 2 1+ 200 MeV Λ 2 m t m 0 6 (i−w) 4(1+2w) 2 , where m 0 ≡[ 16 2 π(0.2 GeV) G F ] 1 3 =107 GeV , and w≡ M W 2 m t 2 . This energy is just above threshold for m t = 100 GeV but for m t = 150 GeV increases to 700 GeV.
