Description
The MHV Lagrangian is the Yang-Mills Lagrangian quantized on the light
cone, where the two transverse gluonic degrees of freedom have been
canonically transformed to a set of new fields, in which the vertices
become a series of the maximally helicity violating (MHV) amplitudes
continued off-shell. The usage of the MHV vertices to construct
amplitudes is also known as the Cachazo-Svrcek-Witten (CSW) method.
After a review of these ideas I will discuss properties of the
transformation leading to the MHV Lagrangian, in particular I will argue
that the solution to the field transformation has a form of certain Wilson line.
I will also discuss some consequences of that fact.
