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.
