Resumen
The purpose of the present work is test the Implicit Regularization Technique in massless theories and to investigate if the treatmente requires modifications to meat the IR divergences from the one used the treat UV divergences. One learns that no modifications are needed and that the cancellation of UV divergences requires a subtle relation between divergent and finit output of the amplitudes. We also obtein the anomalous dimension of the theory.
