# Three Jet Events - Electron Positron Annihilation

In a three jet event, a high transverse momentum gluon is emitted before the hadronisation of quarks takes place. What is the intermediate process that the gluon undergoes before it hadronises?

I am imagining that it will produce a $q \bar q$ pair, but if that is the case, why do we see three distinct jets and not four?

Is it due to a small opening angle between the quarks?
