Abstract
We investigate the possibilities of finding the effects of the littlest Higgs (LH) model on the process e + e − → µ+µ− at the leading-order at a possible Z 0-factory. We study the impacts of the LH model on the observables, such as, the total cross section, the distribution of the transverse momentum of µ−, and the forward-backward charge asymmetry of µ− in polarized and unpolarized electron-positron collision modes. Besides, we analyze the relations between the observables and the LH model parameters, and discuss the observables of process e + e − → µ+µ− in different incoming electron-positron polarization modes. We conclude that one could observe the effects contributed by the LH model on the process e + e − → µ+µ− in a reasonable parameter space, or might put more stringent constraints on the LH parameters in the future experiments at the possible Z 0-factory.
