13. Apparently, the TC hypothesis is not excluded by CERN Higgs data....

However, is there further data that supports the TC hypothesis?

For the actual paper and some other background information on TC from 2007, see the following:

Technicolor Higgs boson in the light of LHC data

Abstract


We consider scenarios in which the 125 GeV resonance observed at the Large Hadron Collider is a Technicolor (TC) isosinglet scalar, the TC Higgs and explore the viable parameter space of the effective Higgs boson couplings within the TC Higgs scenario using the latest LHC data. By comparison with quantum chromodynamics, we argue that the couplings of the TC Higgs to the massive weak bosons are very close to the standard model (SM) values. The couplings to photons and gluons are model-dependent, but close to the SM values in several TC theories. The couplings of the TC Higgs to SM fermions are due to interactions beyond TC, such as extended technicolor: if such interactions successfully generate mass for the SM fermions, we argue that the couplings of the latter to the TC Higgs are also SM-like. We suggest a generic parametrization of the TC Higgs interactions with SM particles that accommodates a large class of TC models, and we perform a fit of these parameters to the Higgs LHC data. The fit reveals regions of the parameter space where the form factors have an order-one absolute value at the 95% CL, in agreement with expectations in TC theories. This indicates that the discovered Higgs boson is consistent with the TC Higgs hypothesis for several TC theories.
