Abstract
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 emission and non-perturbative fragmentation does introduce a correlation, however. To illustrate the size of these effects, we study the multiplicity as a function of the angle between the b and b jets, close to the tt threshold. Also potential uncertainties in top mass determinations are briefly addressed.
