Technicolor and other QCD-like theories at next-to-next-to-leading
order
Abstract
We calculate the vacuum-expectation-value, the meson mass and the meson
decay constant to next-to-next-to-leading-order in the chiral expansion
for QCD-like theories with general $N_F$ degenerate flavours for the cases
with a complex representation, a real and a pseudoreal representation,
i.e. with global symmetry and breaking patters $SU(N_F)_L\times
SU(N_F)_R\to SU(N_F)_V$, $SU(2N_F)\to SO(2N)$ and $SU(2N_F)\to Sp(2N_F)$.
These calculations should be useful for lattice calculations for dynamical
electroweak symmetry breaking and related cases.
