We study the minimal model of conformal technicolor, an SU(2) gauge theory near a strongly coupled conformal fixed point, with conformal symmetry softly broken by technifermion mass terms. Conformal symmetry breaking triggers chiral symmetry breaking in the pattern SU(4) → Sp(4), which gives rise to a pseudo-Nambu-Goldstone boson that can act as a composite Higgs boson. The top quark is elementary, and the top and electroweak gauge loop contributions to the Higgs mass are cut off entirely by… 

Flavor in minimal conformal technicolor

We construct a complete, realistic, and natural UV completion of minimal conformal technicolor that explains the origin of quark and lepton masses and mixing angles. As in “bosonic technicolor,” we

Dark matter in (partially) composite Higgs models

A bstractWe construct composite and partially composite Higgs models with complex pseudo-Nambu-Goldstone (pNGB) dark matter states from four-dimensional gauge-Yukawa theories with strongly

Vector and axial-vector resonances in composite models of the Higgs boson

A bstractWe provide a non-linear realisation of composite Higgs models in the context of the SU(4)/Sp(4) symmetry breaking pattern, where the effective Lagrangian of the spin-0 and spin-1 resonances

Fundamental composite (Goldstone) Higgs dynamics

A bstractWe provide a unified description, both at the effective and fundamental Lagrangian level, of models of composite Higgs dynamics where the Higgs itself can emerge, depending on the way the

Very light dilaton and naturally light Higgs boson

A bstractWe study very light dilaton, arising from a scale-invariant ultraviolet theory of the Higgs sector in the standard model of particle physics. Imposing the scale symmetry below the

Holographic models of composite Higgs in the Veneziano limit. Part I. Bosonic sector

Abstract We study strongly-coupled, approximately scale-invariant gauge theories, which develop a mass gap in the infrared. We argue that a large number of fermion flavours is most suitable to

Partially composite Higgs models: phenomenology and RG analysis

A bstractWe study the phenomenology of partially composite-Higgs models where electroweak symmetry breaking is dynamically induced, and the Higgs is a mixture of a composite and an elementary state.

A Seiberg Dual for the MSSM: Partially Composite W and Z

We examine the possibility that the SU(2)L gauge group of the standard model appears as the dual \magnetic" gauge group of a supersymmetric gauge theory, thus the W and Z (and through mixing, the

Technically natural Higgs boson from Planck scale

We propose UV complete (partially) composite Higgs models with compositeness scale up to the Planck scale assisted by a novel mechanism. This mechanism is based on softly breaking a global Z 2

Partially supersymmetric composite Higgs models

We study the idea of the Higgs as a pseudo-Goldstone boson within the framework of partial supersymmetry in Randall-Sundrum scenarios and their CFT duals. The Higgs and third generation of the MSSM



Higgs as a holographic pseudo-Goldstone boson

The Intermediate Higgs

Two paradigms for the origin of electroweak superconductivity are a weakly coupled scalar condensate, and a strongly coupled fermion condensate. The former suffers from a finetuning problem unless

The S-parameter in holographic technicolor models

We study the S parameter, considering especially its sign, in models of elec- troweak symmetry breaking (EWSB) in extra dimensions, with fermions localized near the UV brane. Such models are

Conformal Technicolor

We point out that the flavor problem in theories with dynamical electroweak symmetry breaking can be effectively decoupled if the physics above the TeV scale is strongly conformal, and the electroweak

Towards a realistic model of Higgsless electroweak symmetry breaking.

The model presented here can be viewed as the AdS dual of a (walking) technicolorlike theory, in the sense that it is the presence of the IR brane itself that breaks electroweak symmetry, and not a localized Higgs on theIR brane (which should be interpreted as a composite Higgs model).
