v10 v11 26 26 * 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 twoindex symmetric representation. 27 27 28 Our implementation makes use of the effective lowenergy 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 spinone resonances. For these states the effective theories of MWT and NMWT coincide.28 Our implementation makes use of the effective lowenergy model containing scalars, pseudoscalars, vector mesons and other fields predicted by the models.

The directory is provided by a README file with the instructions on the usage. 71 '''...Say something about Tuomas HGG'''72 70 73 71 The model file implements a (linear) effective theory for the spinzero and spinone 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 spinone triplets, which mix with each other and with the electroweak gauge bosons. … … 102 100 * pp>mu+mu at 1400 GeV 103 101 104 Furthermore, the matrix element generated for qq~>mu+mu was checked by hand for a few phase space points.102 Furthermore, the matrix elements generated for 105 103 106 '''Toumas also crosschecked some associate production processes (i.e. Wstrahlung from technirho)''' 104 * l+l>!r1,!r2>l+l 105 * uu~>!r1,!r2>l+l 106 * uu~>!r1>dd~ 107 * l+l>!r1>uu~g 108 * l+vl>W>WH and lvl>W+>W+H 109 110 were checked by hand for a few phase space points. 111 112 113 114 === Extensions === 115 116 * CCCCCCCCC.fr is an extension introducing the effective coupling HGG (Higgs + two gluons) arising at loop level. 117 * !MadGraph calculator for HGG 118 119 '''This file has to be loaded together with the MWT.fr.'''
