Calculating the running coupling in strong electroweak models

Understand

One possibility for Beyond Standard Model physics is a new strongly-interacting gauge theory.

• One way to determine if a non-abelian gauge theory is QCD-like or conformal is to measure the running of the renormalized gauge coupling.
• We define the renormalized coupling from Wilson loop ratios, and measure these ratios via lattice simulations.
• We test this method in SU(3) pure gauge theory and show some first results for simulations with dynamical fermions in the fundamental representation.
