TLDR
In this article, the authors discuss possible searches for the new particles predicted by Little Higgs Models at the LHC using a simulation of the ATLAS detector and demonstrate how the predicted quark, gauge bosons and additional Higgs bosons can be found and estimate the mass range over which their properties can be constrained.
Abstract
We discuss possible searches for the new particles predicted by Little Higgs Models at the LHC. By using a simulation of the ATLAS detector, we demonstrate how the predicted quark, gauge bosons and additional Higgs bosons can be found and estimate the mass range over which their properties can be constrained.

Little hierarchy, little higgses, and a little symmetry

TL;DR: In this paper, a new symmetry, denoted as T-parity, under which all heavy gauge bosons and scalar triplets are odd, can remove all the tree-level contributions to the electroweak observables and therefore make the little Higgs theories completely natural.

Little Higgs models and their phenomenology

TL;DR: In this paper, the Littlest Higgs Model (LHMM) is introduced, which is based on the collective symmetry breaking mechanism of the Higgs boson and remains perturbative until a scale of order 10 TeV.

The Minimal Moose for a Little Higgs

TL;DR: In this article, the authors presented the minimal theory space model of electroweak symmetry breaking, with two sites and four link fields, and the minimal set of fermions, which is the first alternative to weak-scale supersymmetry with naturally light Higgs fields.

Phenomenology of the little Higgs model

TL;DR: In this article, the authors study the low-energy phenomenology of the LHiggs model, and identify sources of the corrections to low energy observables, discuss model-dependent arbitrariness, and outline some possible directions of extensions of the model to evade the precision electroweak constraints.

CompHEP - a package for evaluation of Feynman diagrams and integration over multi-particle phase space. User's manual for version 33

TL;DR: CompHEP as discussed by the authors is a package for automatic calculations of elementary particle decay and collision properties in the lowest order of perturbation theory (the tree approximation), which is the main idea prescribed into the CompHEP is to make available passing on from the Lagrangian to the final distributions effectively with a high level of automation.

Big Corrections from a Little Higgs

TL;DR: In this paper, the tree-level expressions for the electroweak precision observables in the littlest Higgs model were calculated and a global fit was performed to the experimental data and it was shown that throughout the parameter space the symmetry breaking scale is bounded by 95% C.L.

The little Higgs from a simple group

TL;DR: In this paper, the Higgs boson is a pseudo-Nambu-Goldstone boson and the potential contains a Higgs quartic coupling which does not introduce one-loop quadratic divergences.
