Supported by Spanish Grant MINECO: FPA2016-75654-C2-1-P and Carried out in the Inspiring Atmosphere of the IPARCOS Institute for Particles and CosmologyWe reexamine the dynamical generation of mass for fermions charged under various Lie groups with equal charge and mass at a high Grand Unification scale, extending the Renormalization Group Equations in the perturbative regime to two loops and matching to the Dyson-Schwinger Equations in the strong coupling regime.engjournal articlehttp://dx.doi.org/10.1088/0253-6102/71/4/410https://iopscience.iop.org/open access53Quark-gluon vertexMass.Física (Física)22 Física
