Technicolor and other QCD-like theories at next-to-next-to-leading order

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 NF degenerate flavours for the cases with a complex representation, a real and a pseudoreal representation, i.e. with global symmetry and breaking patters SU(NF)L x SU(NF)R → SU(NF)V, SU(2NF) → SO(2N) and SU(2NF) → Sp(2NF). These calculations should be useful for lattice calculations for dynamical electroweak symmetry breaking and related cases.
