We investigate the longitudinal WW scattering in models of dynamical electroweak symmetry breaking featuring a spin-one axial and vector state and a composite Higgs boson. We also investigate the effects of a composite spin-two state which has the same properties of a massive graviton. Any model of dynamical electroweak symmetry breaking will feature, depending on the dynamics, some or all of these basic resonances as part of the low energy spectrum. We suggest how to take limits in the…

Supersymmetric Extension of Technicolor & Fermion Mass Generation
Abstract We provide a complete extension of Minimal Walking Technicolor able to account for the Standard Model fermion masses. The model is supersymmetric at energies greater or equal to the
Unnatural origin of fermion masses for technicolor
We explore the scenario in which the breaking of the electroweak symmetry is due to the simultaneous presence and interplay of a dynamical sector and an unnatural elementary Higgs. We introduce a low
Phenomenology and cosmology of an electroweak pseudo-dilaton and electroweak baryons
A bstractIn many strongly-interacting models of electroweak symmetry breaking the lowest-lying observable particle is a pseudo-Goldstone boson of approximate scale symmetry, the pseudo-dilaton. Its
Composite Resonances effects on EWPT and Higgs diphoton decay rate
Abstract In scenarios of strongly coupled electroweak symmetry breaking, heavy composite particles of different spin and parity may arise and cause observable effects on signals that appear at loop
Composite vectors in Higgless models at the LHC
In the context of a strongly coupled Electroweak Symmetry Breaking, composite triplet of heavy vectors degenerate in mass belonging to the SU(2)L+R adjoint representation may arise from a new strong
Unitarity implications of a diboson resonance in the TeV region for Higgs physics
We investigate the implications of a putative new resonance in the TeV region coupled to the weak bosons. By studying perturbative unitarity in longitudinal WW scattering, we find that a weakly
We analyze the constraints on the the vacuum polarization of the Standard Model gauge bosons from a minimal set of flavor observables valid for a general class of models of dynamical electroweak
Conformal Dynamics for TeV Physics and Cosmology
We introduce the topic of dynamical breaking of the electroweak symmetry and its link to unparticle physics and cosmology. The knowledge of the phase diagram of strongly coupled theories plays a
Dynamical Electroweak Symmetry Breaking at the LHC on Supercomputers and in the Sky (Asymmetric Dark Matter)
I briefly review the basic challenges and virtues of models breaking the electroweak symmetry dynamically. I will then introduce the (ultra) minimal walking technicolor models whose construction has
Top quark effects in composite vector pair production at the LHC
In the context of strongly coupled Electroweak Symmetry Breaking, composite light scalar singlet and composite triplet of heavy vectors may arise from an unspecified strong dynamics and the
