RT Journal Article T1 Chiral symmetry breaking for fermions charged under large Lie groups. A1 Llanes Estrada, Felipe José A1 Salas Bernárdez, Alexandre AB We 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.
