Light-front gauge is the most popular one to work with fundamental interactions, due to its characteristic maximum kinematical Poincare operators that it allows. However, it is also known to be one of the trickiest gauges one can work with for gauge theories, due to its singular nature. So, in terms of perturbative calculations in the light-front, there are only a few published and tabulated results for the pertinent Feynman integrals, mostly involving massless integrals. And the majority of the results given are only for the divergent parts of them and the complete closed form (or with the finite parts) of these are not known. In this manuscript, we use the technique of negative dimensional integration (NDIM) for the simplest of the one-loop massive integrals as a working bench for massive Feynman integrals in the light-front and show that novel results for the finite parts not known before are obtained.
