Gauge coupling unification via a technicolor model

We show that the recently proposed minimal walking technicolor theory together with a small modification of the standard model fermionic matter content leads to an excellent degree of unification of the gauge couplings. We compare the degree of unification with various time-honored technicolor models and the minimal supersymmetric extension of the standard model. We find that, at the one-loop level, the new theory provides a degree of unification higher than any of the other extensions above. The phenomenology of the present model is very rich with various potential dark matter candidates. © 2007 The American Physical Society.
