Content

Grand unified theories (GUTs) are an attempt to unifiy the gauge interactions of the standard model. We show that conventional perturbation theory is insufficient to correctly predict the particle spectrum in many GUTs, and how a correct result is obtained from strict gauge invariance and the Fröhlich-Morchio-Strocchi mechanism.

We use lattice simulations for a toy GUT to demonstrate the above reasoning. For this purpose we investigate various quantum number channels. We validate the failure of ordinary perturbation theory, and the correctness of the improved predictions.

Our procedure can therefore be used to rule out certain BSM theories, especially, but not only, of GUT type.
