Surveillance on the light-front gauge fixing Lagrangians

Abstract

In this work we propose two Lagrange multipliers with distinct coefficients for the light-front gauge that leads to the complete (non-reduced) propagator. This is accomplished via $(n\cdot A{)}^2+(\partial \cdot A{)}^2$ terms in the Lagrangian density. These lead to a well-defined and exact though Lorentz non invariant light front propagator.
