A new Wilson line-based action for gluodynamics

Abstract: We perform a canonical transformation of fields that brings the Yang-Mills action in the light-cone gauge to a new classical action, which does not involve any triple-gluon vertices. The lowest order vertex is the four-point MHV vertex. Higher point vertices include the MHV and $$ \overline{\mathrm{MHV}} $$ MHV ¯ vertices, that reduce to the corresponding amplitudes in the on-shell limit. In general, any n-leg vertex… Show more

“…Triple point vertices are not very effective building blocks for calculating amplitudes, and, actually they do not constitute any physical amplitude themselvesin the on-shell limit they are zero (for real momenta). Motivated by the geometric considerations mentioned before and the above arguments we proposed in [8] another set of field transformations that lead to a new action.…”
