Colour Reconnection from Soft Gluon Evolution

Understand

We consider soft gluon evolution at the amplitude level to expose the structure of colour reconnection from a perturbative point of view.

• Considering the cluster hadronization model and an universal Ansatz for the soft anomalous dimension we find strong support for geometric models considered earlier.
• We also show how reconnection into baryonic systems arises, and how larger cluster systems evolve.
• Our results provide the dynamic basis for a new class of colour reconnection models for cluster hadronization.
