Composite Higgs models are promising candidate models to address the long-standing naturalness
problem in the Standard Model. Among them, the most minimal one is the SU(2) with 2 flavours
of fermions in the fundamental representation of the gauge group. An important prediction in
these models is the existence of resonance spectrum in vector boson scattering. Here we study the
lowest such resonance, which is the equivalent of rho resonance in QCD. We describe the scan of
the parameter space using the clover-improved Wilson fermions with Symanzik improved gauge
action and then show the first results for the mass and width of the rho resonance in this model.
