Pérez-Lorenzana Física, Astronomía y Matemáticas renormalization renormalization Quantum field theory Quantum field theory radiative corrections The most general method to regularize Feynman’s integrals in quantum field theory is Dimensional Regularization, in which the most common way to evaluate the associated integral involves Beta functions. We present a new method to evaluate the integral through the residue theorem. We apply our method to a toy model on universal extra dimensions and show that radiative corrections changes the shiftmass between zero and Kaluza-Klein excited modes. 2015 artículo científico 0035-001X https://www.redalyc.org/articulo.oa?id=57036862013 en http://www.redalyc.org/revista.oa?id=570 Revista Mexicana de Física application/pdf Sociedad Mexicana de Física A.C.
