    2626* Next to Minimal Walking Technicolor (NMWT) is a similar extension, but based on the gauge group SU(3) technicolor with a doublet of Dirac fermions in the two-index symmetric representation.

    28 Our implementation makes use of the effective low-energy model containing scalars, pseudoscalars, vector mesons and other fields predicted by the models. The implemented model is the simplest one, which contains only the composite states, which are expected to be the most important for collider phenomenology. These are the composite Higgs, and the vector and axial spin-one resonances. For these states the effective theories of MWT and NMWT coincide.

    7371The model file implements a (linear) effective theory for the spin-zero and spin-one sectors in technicolor, with the minimal SU(2),,L,, x SU(2),,R,, -> SU(2),,V,, chiral symmetry breaking pattern. The strong technicolor interactions is linked to the electroweak sector as stipulated by the electroweak gauge transformations of the techniquarks. The modifications to the effective theory due to the electroweak interactions are mostly small. The composite scalar sector contains the composite Higgs boson and a triplet of massless technipions, which are eaten by the heavy gauge boson Z and W. The Higgs is expected to be relatively light (mass less than 500 GeV). We also have vector and axial spin-one triplets, which mix with each other and with the electroweak gauge bosons.
