Ultra-Violet Finiteness of the N = 4 Model

  • Stanley Mandelstam
Part of the Studies in the Natural Sciences book series (SNS, volume 20)


The N = 4 model is examined in light-cone coordinates. The advantage of such coordinates is that they can easily be applied to extended supersymmetries. In a certain form of the light-cone gauge, the perturbation expansion of the N = 4 model is free of ultraviolet divergences. As a consequence, the β-function vanishes in any order of perturbation theory in any gauge.
