Dynamical symmetry breaking in an E6 GUT model
Description
Dynamical symmetry breaking is studied in an E6 GUT model of a single generation of fermions with strong 4-fermi interactions. The effective potential is analyzed analytically by the help of Michel's conjecture and the result is confirmed numerically. We find that the E6 symmetry is spontaneously broken either to F4 or to Sp(8) or G2 or SU(3), depending on which of the 4-fermi coupling constants G27 and G351 in the 27/351 channels is stronger. The possibilities for obtaining other type of breaking patterns are also discussed. (author)
