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)\_LSU(N\_F)\_RSU(N\_F)\_V\$,
\$SU(2N\_F)SO(2N)\$ and \$SU(2N\_F)Sp(2N\_F)\$. These calculations should be
useful for lattice calculations for dynamical electroweak symmetry breaking and
related cases.
