Description
SU(2) gauge theories with two quark flavours in the fundamental
representation are among the most promising theories of composite dynamics
describing the electroweak sector. Three out of five Goldstone bosons in
these models become the longitudinal components of the W and Z bosons giving
them mass. Like in QCD we expect a spectrum of excitations which appear as
resonances in vector boson scattering, in particular the vector resonance
corresponding to the rho-meson in QCD.
In this talk I will present the preliminary results of the first calculation
of the rho-meson decay width in this theory, which is analogous to rho to
two pions decay calculation in QCD. The results presented were calculated
using 2 moving frames on s single ensemble. Future plans include using 3
moving frames on a larger set of ensembles to extract the resonance
parameters more reliably and also take the chiral and continuum limits.
