Possible discrepancies in the spectrum of GUT models
November 21, 2022
Analytical investigations and lattice simulations suggested that the spectrum of observable particles in BSM-like theories may differ from the elementary ones. We consider a GUT-like toy theory, which showed such qualitative discrepancies in exploratory lattice simulations, and perform a detailed quantitative investigation of its physical spectrum, covering 18 different channels in total. We find indeed a substantial different spectrum than the elementary one. In particular, stable states with quantum numbers different from the elementary ones are observed.
