The light composite Higgs boson in strong extended technicolor
Abstract
This paper extends an earlier one describing the Higgs boson H as a light composite scalar in a strong extended technicolor model of electroweak symmetry breaking. The Higgs mass M _{H} is made much smaller than Λ _{ETC} by tuning the ETC coupling very close to the critical value for electroweak symmetry breaking. The technicolor interaction, neglected in the earlier paper, is considered here. Its weakness relative to extended technicolor is essential to understanding the lightness of H compared to the lowlying spinone technihadrons. Technicolor cannot be completely ignored, but implementing technigluon exchange together with strong extended technicolor appears difficult. We propose a solution that turns out to leave the results of the earlier paper essentially unchanged. An argument is then presented that masses of the spinone technifermion bound states, ρ _{H} and a _{H} , are much larger than M _{H} and, plausibly, controlled by technicolor. Assuming M _{ρH} and M _{aH} are in the TeVenergy region, we identify ρ _{H} and a _{H} with the diboson excesses observed near 2 TeV by ATLAS and CMS in LHC Run 1 data, and we discuss their phenomenology for Runs 2 and 3.

We compute an effective action for a composite Higgs boson formed by new fermions belonging to a general technicolor nonAbelian gauge theory, using a quite general expression for the fermionic selfenergy that depends on a certain parameter ({alpha}), that defines the technicolor theory from the extreme walking behavior up to the one with a standard operator product expansion behavior. We discuss the values of the trilinear and quadrilinear scalar couplings. Our calculation spans all the possible physical possibilities for mass and couplings of the composite system. In the case of extreme walking technicolor theories we verify that it is possiblemore »

Z boson propagator correction in technicolor theories with extended technicolor effects included
We calculate the Z boson propagator correction, as described by the S parameter, in technicolor theories with extended technicolor interactions included. Our method is to solve the BetheSalpeter equation for the requisite currentcurrent correlation functions. Our results suggest that the inclusion of extended technicolor interactions has a relatively small effect on S. 
Selfconsistent dynamics of a light composite scalar Higgs boson
We apply a simple approximate relativistic amplitudeunitarization generalization of nonrelativistic Schroedingerequation dynamics to the scattering of longitudinal massdegenerate [ital W] and [ital Z] gauge bosons. The strong energy dependence of our amplitude near the [ital WW] threshold then makes possible a nonperturbative selfconsistent nonelementary neutral Higgs scalar bound state ([ital H]) just below this threshold. We must, however, include a constant term approximating highenergy inelastic effects in addition to [ital H] exchange. Everything, including the [ital H] mass, can then be determined in terms of the small phenomenological [ital WWH] coupling and [ital W] mass, which serves to set themore »

The strong energy dependence of this amplitude near the WW threshold then makes possible a nonperturbative selfconsistent nonelementary neutral Higgs scalar bound state (H) just below this threshold. The authors must, however, include a constant term approximating highenergy inelastic effects in addition to H exchange. Everything, including the H mass, can then be determined in terms of the small phenomenological WWH coupling and W mass, which serves to set the energy scale of themore » 
Light composite Higgs boson from higher representations versus electroweak precision measurements: Predictions for CERN LHC
We investigate theories in which the technifermions in higher dimensional representations of the technicolor gauge group dynamically break the electroweak symmetry of the standard model. Somewhat surprisingly, for the twoindex symmetric representation of the gauge group the lowest number of techniflavors needed to render the underlying gauge theory quasiconformal is two. This is exactly one doublet of technifermions with respect to the weak interactions promoting these theories to ideal candidates of walking type technicolor models. From the point of view of the weak interactions the two techniflavor theory has a Witten anomaly, which we cure by introducing a fourth familymore »
