Neutrinos in the Simplest Little Higgs Model
نویسنده
چکیده
The simplest little Higgs model based on a gauge group SU(3)color×SU(3)weak× U(1)X contains three vector-like lepton singlets with electric charge 0 below electroweak energy scale. They are counter partners of the first component in the leptonic triplet of SU(3)L for each generation. Due to Yukawa couplings the neutral singlets not only have a Dirac mass, but also couple to the neutrinos. Thus the neutrino mass eigenstates are different from the neutrino weak eigenstates.

Singlet scalar dark matter in noncommutative space
In this paper, we examine the singlet scalar dark matter annihilation to becoming the Standard Model particles in the non-commutative space. In the recent decades, many candidates of dark matter have been offered, but our information about the nature of dark matter is still limited. There are such particle candidates as scalar matetr, fermion, boson, gauge boson, etc.; however, they have nei...
متن کاملLittle Higgses and Turtles
We present an ultra-violet extension of the “simplest little Higgs” model. The model marries the simplest little Higgs at low energies to two copies of the “littlest Higgs” at higher energies. The result is a weakly coupled theory below 100 TeV with a naturally light Higgs. The higher cutoff suppresses the contributions of strongly coupled dynamics to dangerous operators such as those which ind...
متن کاملSmallness of Leptonic θ 13 and Discrete Symmetry
The leptonic mixing angle θ 13 is known to be small. If it is indeed tiny, the simplest explanation is that charged leptons mix only in the µ − τ sector and neutrinos only in the 1 − 2 sector. We show that this pattern may be explained by the discrete symmetry Z 2 × Z 2 of a complete Lagrangian, which has 2 Higgs doublets and 2 Higgs triplets (or 2 heavy right-handed singlet neutrinos). In the ...
متن کاملStudy of the simplest realistic Higgs sector in quark-lepton symmetric models.
A discrete symmetry between quarks and (generalized) leptons can exist in nature, and its spontaneous symmetry breaking scale can be as low as a few TeV. Such a discrete symmetry also has interesting implications for how electroweak symmetry is spontaneously broken, because the simplest version of the theory requires two electroweak Higgs doublets rather than one in order to provide acceptable ...
متن کاملBounds on the Simplest Little Higgs Model Mass Spectrum Through Z Leptonic Decay
We derive the leptonic neutral current in the simplest little Higgs model and compute the contribution of the model to the decay width Z → e+e−. Using the precision electroweak data we obtain a strong lower bound f ≥ 5.6 TeV at 95% C.L. on the characteristic energy scale of the model. It results in a lower bound for the new gauge bosons W ′± and Z ′ as being MW ′± ≥ 2.6 TeV and MZ′ ≥ 3.1 TeV, r...
