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

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

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

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
