Description

In this talk I will discuss a new form of the action for Yang-Mills theory based on Wilson lines. Starting from the Yang-Mills action on the light cone, it can be showed that a canonical transformation of fields leads to a new form of the action which does not involve any triple-gluon vertices. The canonical transformation of the fields can be expressed as path ordered exponential of fields and their functional derivatives. New action can be used to compute tree-level amplitudes in very economical way as presented on few examples.
