Colour correlations and multiplicities in top events
In events of the type e+e- → tt → bW+bW-, particle production could depend in a non-trivial way on the kinematics of the process. Energetic perturbative gluon radiation can be generated (when kinematically allowed) by the original tt system and by the t → bW+ and t → bW- decays, with negligible interference between the production and decay between the t and t decays. Soft perturbative gluon emissi
