In a non-perturbative gauge-invariant formulation of grand-unified theories all low energy vector states need to be composite with respect to the high-scale gauge group, including the photon. We investigate this by using lattice methods to spectroscopically analyze the vector channel in a toy grand-unified theory, an SU(2) adjoint Higgs model. Our results support indeed the existence of a massless composite vector particle.

Exploring SU(3)-Higgs theories
The requirement of manifest gauge invariance leads to a conflict between perturbative and nonperturbative predictions for the low-energy spectra of grand-unified theories. These conflicts already…
Testing the mechanism of lepton compositeness
Strict gauge invariance requires that physical left-handed leptons are actually bound states of the elementary left-handed lepton doublet and the Higgs field within the standard model. That they…

Analytical relations for the bound state spectrum of gauge theories with a Brout-Englert-Higgs mechanism
We apply the method proposed by Frohlich, Morchio, and Strocchi to analyze the bound state spectrum of various gauge theories with a Brout-Englert-Higgs mechanism. These serve as building blocks for…
