Colour Connection and Diquark Fragmentation in e^+e^- \to c \bar c q \bar q \to h's Process

Wei Han, Shi-Yuan Li, Zong-Guo Si +1

The hadronization effects induced by different colour connections of $c\bar{c}q\bar{q}$ system in $e^{+}{e}^{-}$ annihilation are investigated by a toy model where diquark fragmentation…
