The authors' main claim In the mechanical analog, it is clear that even for arbitrary patterns of symmetry breaking, it is not possible (in the perturbative regime) to raise the Higgs mass by a large factor while keeping the $S$ parameter small.

The abstract, sentence by sentence

arXiv listing abstract v2. Results and the main claim are underlined; show every role.

Motivated by recent works on ``Higgsless theories,'' I discuss an $SU(2)_0\times SU(2)^{N}\times U(1)$ gauge theory with arbitrary bifundamental (or custodial SU(2) preserving) symmetry breaking between the gauge subgroups and with ordinary matter transforming only under the U(1) and $SU(2)_0$. When the couplings, $g_j$, of the other SU(2)s are very large, this reproduces the standard model at the tree level. I calculate the $W$ and $Z$ masses and other electroweak parameters in a perturbative expansion in $1/g_j^2$, and give physical interpretations of the results in a mechanical analog built out of masses and springs. In the mechanical analog, it is clear that even for arbitrary patterns of symmetry breaking, it is not possible (in the perturbative regime) to raise the Higgs mass by a large factor while keeping the $S$ parameter small.

The paper

Original abstract

Motivated by recent works on ``Higgsless theories,'' I discuss an $SU(2)_0\times SU(2)^{N}\times U(1)$ gauge theory with arbitrary bifundamental (or custodial SU(2) preserving) symmetry breaking between the gauge subgroups and with ordinary matter transforming only under the U(1) and $SU(2)_0$. When the couplings, $g_j$, of the other SU(2)s are very large, this reproduces the standard model at the tree level. I calculate the $W$ and $Z$ masses and other electroweak parameters in a perturbative expansion in $1/g_j^2$, and give physical interpretations of the results in a mechanical analog built out of masses and springs. In the mechanical analog, it is clear that even for arbitrary patterns of symmetry breaking, it is not possible (in the perturbative regime) to raise the Higgs mass by a large factor while keeping the $S$ parameter small.

Fitting a right-handed quark mixing matrix to charged-current data resolves the |V_ub| tension but forces S_psiK = sin 2 beta = 0.77 +/- 0.05, roughly 2 sigma above the measured 0.672 +/- 0.023.

These oblique corrections tend to give large and positive contributions to the $ϵ_3$ (or $S$) parameter, so that it is difficult to conciliate the electroweak bounds with a delay of the unitarity violation scale, [ref] .

An interesting alternative is that of Higgsless models, or the wide class of theories (see e.g. Ref. [ref] ) where the $SU(2)_L ×U(1)_Y →U(1)_Q$ breaking is generated by some new strong dynamics above the Fermi scale ($v=(√(2)G_F)^-1/2≃246$ GeV).

An interesting alternative to the Higgs mechanism is the wide class of Higgsless models: theories where there are no light scalar particles and the $SU(2)_L ×U(1)_Y →U(1)_Q$ breaking is generated by new strong dynamics above the electroweak scale (see e.g. Ref. [ref] ).
