We show that certain little Higgs models with symmetry breaking SU(N){yields}SO(N) for N{>=}4 admit topologically stable solitons that may contribute to cosmological dark matter. We have constructed a spherically symmetric soliton and estimated its mass in the case of SU(5){yields}SO(5). Its mass is estimated to be around 10.3 TeV. Whether this particle is a fermion or a boson depends on the value of an integer-valued parameter of the underlying theory, analogous to the number of colors of QCD…

Dangerous skyrmions in little Higgs models

A bstractSkyrmions are present in many models of electroweak symmetry breaking where the Higgs is a pseudo-oldstone boson of some strongly interacting sector. They are stable, composite objects whose

The little skyrmion: new dark matter for little Higgs models

We study skyrmions in the littlest Higgs model and discuss their possible role as dark matter candidates. Stable massive skyrmions can exist in the littlest Higgs model also in absence of an exact

Partially composite dark matter

A bstractIn a class of theories where the Higgs field emerges as a pseudo Nambu-Goldstone boson, it is often assumed that interactions to generate the top Yukawa coupling provide the Higgs potential

Topological terms in Composite Higgs models

A bstractWe apply a recent classification of topological action terms to Composite Higgs models based on a variety of coset spaces G/H and discuss their phenomenology. The topological terms, which

Topological Dark Matter from the Theory of Composite Electroweak Symmetry Breaking

The lightest electroweak baryon as a topological object is investigated by using a general effective Lagrangian of composite electroweak symmetry breaking and the spin-independent electroweak

Gauge theories of partial compositeness: scenarios for Run-II of the LHC

A bstractWe continue our investigation of gauge theories in which the Higgs boson arises as a pseudo-Nambu-Goldstone boson (pNGB) and top-partners arise as bound states of three hyperfermions. All

Topological effects in particle physics phenomenology

This thesis is devoted to the study of topological effects in quantum field theories, with a particular focus on phenomenological applications. We begin by deriving a general classification of

Classical skyrmions in SU(N)/SO(N) cosets

We construct the skyrmion solutions appearing in the coset spaces SU(N)/SO(N) for N > 2 and compute their classical mass. For N = 3, the third homotopy group $ {\pi_3}\left( {{{{{\text{SU}}(3)}}

Perturbative and Nonperturbative Aspects of the Phenomenology of Composite Higgs Models

The discovery of the Higgs boson announced by CERN on July 4th 2012 was expected by the particle physics community since a long time. Indirect evidence that a Higgs boson must be present in the mass

Topology in the little higgs models

We investigate the implications of the nontrivial vacuum structure of little Higgs models. In particular, focusing on the littlest Higgs model, we demonstrate the existence of three types of

Neutrino Masses and Mixings in Gauge Models with Spontaneous Parity Violation

Unified electroweak gauge theories based on the gauge group SU(2)/sub L/ x SU(2)/sub R/ x U(1)/sub B/-L, in which the breakdown of parity invariance is spontaneous, lead most naturally to a massive

Electroweak precision constraints on the littlest Higgs model with T parity

We compute the leading corrections to the properties of W and Z bosons induced at the one-loop level in the SU(5)/SO(5) Littlest Higgs model with T parity, and perform a global fit to precision

The Littlest Higgs

We present an economical theory of natural electroweak symmetry breaking, generalizing an approach based on deconstruction. This theory is the smallest extension of the Standard Model to date that

TeV symmetry and the little hierarchy problem

Constraints from precision electroweak measurements reveal no evidence for new physics up to 5–7 TeV, whereas naturalness requires new particles at around 1 TeV to address the stability of the

The Minimal Moose for a Little Higgs

Recently a new class of theories of electroweak symmetry breaking have been constructed. These models, based on deconstruction and the physics of theory space, provide the first alternative to

Little hierarchy, little higgses, and a little symmetry

Little Higgs theories are an attempt to address the ``little hierarchy problem,'' i.e., the tension between the naturalness of the electroweak scale and the precision electroweak measurements showing

Exotic levels from topology in the quantum-chromodynamic effective Lagrangian

Skyrme has shown that the SU(2)xSU(2) chiral model has nontrivial topological sectors with static solutions for suitable Lagrangians. The baryon number B and strangeness of these sectors are studied,
