Description
The SU(2) gauge theory with two massless Dirac flavors
constitutes the building block of several models of
Technicolor. Furthermore it has also been used as a template
for the construction of a natural light asymmetric, or mixed
type, dark matter candidate. We use explicit lattice
simulations to confirm the pattern of chiral symmetry
breaking by determining the Goldstone spectrum and
therefore show that the dark matter candidate can, de facto,
be constituted by a complex Goldstone boson. We also
determine the phenomenologically relevant spin-one and
spin-zero isovector spectrum and demonstrate that it is well
separated from the Goldstone spectrum.
