Grand Unification without Higgs Bosons    [PDF]

Stephen M. Barr, Xavier Calmet

We discuss how a model for the electroweak interactions without a Higgs could
be embedded into a grand unified theory. The requirement of a non-trivial fixed
point in the SU(2) sector of the weak interactions together with the
requirement of the numerical unification of the gauge couplings leads to a
prediction for the value of the SU(2) gauge coupling in the fixed point regime.
The fixed point regime must be in the TeV region to solve the unitarity problem
in the elastic scattering of W bosons. We find that the unification scale is at
about 10^{14} GeV. Viable grand unified theories must thus conserve baryon
number. We discuss how to build such a model without using Higgs bosons.
