We emphasize that the electroweak interactions without a Higgs boson are very similar to quantum general relativity. The Higgs field could just be a dressing field and might not exist as a propagating particle. In that interpretation, the electroweak interactions without a Higgs boson could be renormalizable at the nonperturbative level because of a nontrivial fixed point. Tree-level unitarity in electroweak bosons scattering is restored by the running of the weak scale.

Grand Unification without Higgs Bosons
We discuss how a model for the electroweak interactions without a Higgs could be embedded into a grand unified theory. The requirement of a non-trivial fixed point in the SU(2) sector of the weak
Asymptotically Safe Higgs Inflation
We construct a new inflation model in which the standard model Higgs boson couples minimally to gravity and acts as the inflaton. Our construction of Higgs inflation incorporates the standard model
On weak interactions as short-distance manifestations of gravity
We conjecture that weak interactions are peculiar manifestations of quantum gravity at the Fermi scale, and that the Fermi constant is related to the Newtonian constant of gravitation.In this
Asymptotic safety guaranteed
We study the ultraviolet behaviour of four-dimensional quantum field theories involving non-abelian gauge fields, fermions and scalars in the Veneziano limit. In a regime where asymptotic freedom is
Unitary standard model from spontaneous dimensional reduction and weak boson scattering at the LHC
Spontaneous dimensional reduction (SDR) is a striking phenomenon predicted by a number of quantum gravity approaches which all indicate that the spacetime dimensions get reduced at high energies. In
Running of Planck mass and Higgs VEV in holographic vs. 4-dimensional RG
We compute the scale dependence of the Planck mass and the Higgs VEV using two very different methods: a holographic procedure based on Einstein's equations in five dimensions, with scalar matter
Running coupling in electroweak interactions of leptons from f(R)-gravity with torsion
The f(R)-gravitational theory with torsion is considered for one family of leptons; it is found that the torsion tensor gives rise to interactions having the structure of the weak forces, while the

The lightest of black holes
In this paper, we consider general relativity in the large N limit, where N stands for the number of particles in the model. Studying the resummed graviton propagator in the linearized regime, we


Weak interactions at very high energies: The role of the Higgs-boson mass
We give an S -matrix-theoretic demonstration that if the Higgs-boson mass exceeds M c = ( 8 π 2 / 3 G F ) 1 / 2 , parital-wave unitarity is not respected by the tree diagrams for two-body scattering
Tasi 2009 lectures: The Higgs as a Composite Nambu-Goldstone Boson
This is an introduction to theories where the Higgs is a composite Nambu-Goldstone boson of a new strongly-interacting dynamics not much above the weak scale. A general discussion is presented based
Strength of weak interactions at very high energies and the Higgs boson mass
It is shown that if the Higgs boson mass exceeds Mc=(8π23GF)12 partial-wave unitarity is not respected by the tree diagrams for two-body reactions of gauge bosons, and the weak interactions must
Invisible Higgs boson, continuous mass fields, and unparticle Higgs mechanism
We explore the consequences of an electroweak symmetry breaking sector which exhibits approximately scale invariant dynamics -- i.e., nontrivial fixed point behavior, as in unparticle models. One can
Scales of mass generation for quarks, leptons, and majorana neutrinos.
This work places new upper limits on the scales of fermion mass generation, independent of the electroweak symmetry breaking scale, and finds that the strongest 2-->n limits fall in a narrow range, 3-170 TeV (with n=2-24), depending on the observed fermions.
Topological Aspects of Quantum Chromodynamics
Absolute confinement of its color charges is a natural property of gauge theories such as quantum chromodynamics. On the one hand, it can be attributed to the existence of color-magnetic monopoles, a
Scales of fermion mass generation and electroweak symmetry breaking
The scale of mass generation for fermions (including neutrinos) and the scale for electroweak symmetry breaking (EWSB) can be bounded from above by the unitarity of scattering involving longitudinal
Upper Bound on the Scale of Majorana-Neutrino Mass Generation
We derive a model-independent upper bound on the scale of Majorana-neutrino mass generation. The upper bound is , where v ≃246 GeV is the weak scale and mν is the Majorana-neutrino mass. For neutrino
Recent Developments in Gauge Theories
Almost all theories of fundamental interactions are nowadays based on the gauge concept. Starting with the historical example of quantum electrodynamics, we have been led to the successful unified
