Little Higgs Model Limits from LHC

The status of several prominent model implementations of the Little Higgs paradigm, the Littlest Higgs with and without discrete T-parity as well as the Simplest Little Higgs are reviewed. For this,

Can the 125 GeV Higgs be the Little Higgs?

A bstractAfter the discovery of the Higgs-like boson by the LHC 2012 it is the most important task to check whether this new particle is the Standard Model Higgs boson or something else. In this

Beyond the Standard Higgs at the LHC: present constraints on Little Higgs models and future prospects

This thesis discusses the consistency of different Little Higgs models with the collected collider data as of the summer of 2013. Moreover, future prospects for possible discov- eries and mass

Little Higgs Model Limits from LHC - Input for Snowmass 2013

The status of several prominent model implementations of the Little Higgs paradigm, the Littlest Higgs with and without discrete T-parity as well as the Simplest Little Higgs are reviewed. For this,

A pedagogical review of electroweak symmetry breaking scenarios

The Standard Model Higgs mechanism is discussed, the Higgs sector of the minimal supersymmetric Standard Model is reviewed and three relatively recent ideas: little Higgs, gauge–Higgs unification and Higgsless scenarios are taken up.

μ − e conversion in the Littlest Higgs model with T-parity

Little Higgs models provide a natural explanation of the little hierarchy between the electroweak scale and a few TeV scale, where new physics is expected. Under the same inspiring naturalness

The bestest little Higgs

While little Higgs models provide an interesting way to address the hierarchy problem, concrete models in the literature typically face two major obstacles. First, the mechanism for generating a

LHC signals of T-odd heavy quarks in the Littlest Higgs model

Recently proposed Little Higgs models present a viable solution to the naturalness problem of the Standard Model. An additional discrete symmetry, called T-parity, has been included in the simplest

Little Higgs Models : A Group Theoretic Primer

One of the outstanding problems in particle physics is the solution to the Standard Model hierarchy problem. In essence, this problem seeks to understand why the scale of electroweak symmetry

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



Phenomenology of the littlest Higgs model with T-parity

Little Higgs models offer an interesting approach to weakly coupled electroweak symmetry breaking without fine-tuning. The original little Higgs models were plagued by strong constraints from

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

Phenomenology of the little Higgs model

We study the low-energy phenomenology of the little Higgs model. We first discuss the linearized effective theory of the ``littlest Higgs model'' and study the low-energy constraints on the model

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 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

Constraining the littlest Higgs

Little Higgs models offer a new way to address the hierarchy problem, and give rise to a weakly-coupled Higgs sector. These theories predict the existence of new states which are necessary to cancel

Neutrino masses in composite little Higgs model

The composite little Higgs model, a UV completion for the SU(5)/SO(5) little Higgs model, incorporates supersymmetry into strong gauge dynamics. We extend the study of flavor physics in the model,

Perturbative, non-supersymmetric completions of the little Higgs

The little Higgs mechanism produces a light 100 GeV Higgs while raising the natural cutoff from 1 TeV to 10 TeV. We attempt an iterative little Higgs mechanism to produce multiple factors of 10
