A vector-like heavy quark in the Littlest Higgs model
The Littlest Higgs model contains a new vector-like heavy quark in the up sector. There are two interesting features of its existence. One is that it extends the 3 × 3 CKM matrix in the Standard Model to a 4 × 3 matrix and the other is that it allows Z-mediated flavor changing neutral currents at tree level in the up sector but not in the down sector. We examine a few of possible windows in whi...
متن کاملSingle production of the vector-like top quark in the littlest Higgs model at TeV energy e−γ colliders
The new colored vector-like heavy fermion T is a crucial prediction in little Higgs models, which plays a key role in breaking the electroweak symmetry. The littlest Higgs model is the most economical one among various little Higgs models. In the context of the littlest Higgs model, we study single production of the new heavy vector-like quark via eγ collisions and discuss the possibility of de...
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...
متن کاملThe heavy top quark in the two Higgs doublet model
Constraints on the two Higgs doublet model are presented, assuming a top mass of 174 ± 17 GeV. We concentrate primarily on the “type II” model, where up–type quarks receive their mass from one Higgs doublet, and down– type quarks receive their mass from the second doublet. High energy constraints derived from the W mass, the full width of the Z and the bb̄ partial width of the Z are combined wit...
متن کاملQuark flavour observables in the Littlest Higgs model with T-parity after LHC Run 1
The Littlest Higgs model with T-parity (LHT) belongs to the simplest new physics scenarios with new sources of flavour and CP violation. The latter originate in the interactions of ordinary quarks and leptons with heavy mirror quarks and leptons that are mediated by new heavy gauge bosons. Also a heavy fermionic top partner is present in this model which communicates with the SM fermions by mea...
