Description
Summary:In this paper we discuss the consequences of including a new heavy right-handed neutrino singlet \(N_R\) in the littlest Higgs model. This new state is not connected with the light neutrinos {\it via} the seesaw mechanism. A very interesting property of this extended model is the full coupling of the new neutral gauge boson \(A_H\) to \(N_R\), giving large total cross sections and suggesting a wide range of experimental search for the \(N_R\) at the p p collider CERN-LHC and future electron-positron collider ILC.
