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 the quadratic divergences of the Standard Model. The simplest version of these models, the Littlest Higgs, is based on an SU(5)/SO(5) non-linear sigma model and predicts that four new gauge bosons, ...

متن کاملLittlest Higgs Model and Unitarity Constraints
The Littlest Higgs Model is constrained using the tree-level perturbative arguments, similar to those used to obtain the Higgs mass bound. It is found that demanding that the theory respects perturbative unitarity upto scales of the order of TeV, in turn implies that the scale f , the analog of pion decay constant, is around 4 TeV.
متن کاملPhenomenology of the Littlest Higgs 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 electroweak precision data which required a fine tuning to be reintroduced. An economical solution to this problem is to introduce a discrete symmetry (analogous to R-parity of SUSY) called T-parity. T-par...
متن کاملRight-handed heavy neutrinos in the littlest Higgs model
In this paper we discuss the consequences of including new heavy righthanded neutrino singlets NR in the littlest Higgs model. These new states are not connected with the light neutrinos via the seesaw mechanism. A very interesting property of this extended model is the full coupling of the new neutral gauge boson AH to the right-handed neutrinos NR, giving large total cross sections and sugges...
