چکیده
We implement a one-loop analysis of the ρ parameter in the Left Right Twin Higgs model, including the logarithmically enhanced contributions from both fermion and scalar loops. Numerical results show that the one-loop contributions are dominant over the tree level corrections in most regions of parameter space. The experimentally allowed values of ρ-parameter divide the allowed parameter space into two regions; less than 670 GeV and larger than 1100 GeV roughly, for symmetry breaking scale f . Our numerical analysis significantly reduces the parameter space which are favorably accessible to the LHC.

Neutrinos and Lepton Flavour Violation in the Left-Right Twin Higgs Model
We analyse the lepton sector of the Left-Right Twin Higgs Model. This model offers an alternative way to solve the “little hierarchy” problem of the Standard Model. We show that one can achieve an effective see-saw to explain the origin of neutrino masses and that this model can accommodate the observed neutrino masses and mixings. We have also studied the lepton flavour violation process l1 → ...

Abstract The twin Higgs mechanism has recently been proposed to solve the little hierarchy problem. We study the implementation of the twin Higgs mechanism in left-right models. At TeV scale, heavy quark and gauge bosons appear, with rich collider phenomenology. In addition, there are extra Higgses, some of which couple to both the Standard Model fermion sector and the gauge sector, while other...
متن کاملH and top quark production in the left-right twin higgs model at the LHC
The twin Higgs mechanism has recently been proposed to solve the little hierarchy problem. In the context of the Left-Right twin Higgs(LRTH) model, we discuss single production of the new charged gauge boson W H , which is predicted by the left-right twin Higgs model, in association with top quark at the CERN Large Hadron Collider(LHC). It is found that, for a typical nonzero value of mass mixi...
متن کاملNatural electroweak breaking from a mirror symmetry.
We present "twin Higgs models," simple realizations of the Higgs boson as a pseudo Goldstone boson that protect the weak scale from radiative corrections up to scales of order 5-10 TeV. In the ultraviolet these theories have a discrete symmetry which interchanges each standard model particle with a corresponding particle which transforms under a twin or a mirror standard model gauge group. In a...
متن کاملPair production of charged Higgs bosons in the Left-Right Twin Higgs model at the ILC and LHC
Left-Right twin Higgs(LRTH) model predicts the existence of a pair of charged Higgs φ. In this paper, we study the production of the charged Higgs bosons pair φ at the International Linear Collider(ILC) and the CERN Large Hadron Collider(LHC). The numerical results show that the production rates are at the level of several tens fb at the ILC, the process e+e− → φ+φ− can produce the adequate dis...
متن کاملThe Little Hierarchy in Universal Extra Dimensions
In the standard model in universal extra dimensions (UED) the mass of the Higgs field is driven to the cutoff of the higher-dimensional theory. This re-introduces a small hierarchy since the compactification scale 1/R should not be smaller than the weak scale. In this paper we study possible solutions to this problem by considering five-dimensional theories where the Higgs field potential vanis...
