Littlest Higgs model and associated ZH production at high energy $e^{+}e^{-}$ collider

In the context of the littlest Higgs (LH) model, we consider the Higgs strahlung process $e^{+}e^{-}\to ZH $. We find that the correction effects on this process mainly come from the heavy photon $B'$. If we take the mixing angle parameter $c$ in the range of 0.75 - 1, the contributions of the heavy gauge boson $W_{3}'$ is larger than 6%. In most of the parameter space, the deviation of the total production cross section $σ^{tot}$ from its SM value is larger than 5%, which may be detected in the future high energy $e^{+}e^{-}$ collider (LC) experiments. The future LC experiments could test the LH model by measuring the cross section of the process $e^{+}e^{-}\to ZH $.

Production of the top-pions at the THERA collider based $γp$ collisions

In the framework of the topcolor-assisted technicolor (TC2) models, we study the production of the top-pions $π^{0}_{t}$, $π_{t}^{\pm}$ via the processes $ep\toγc\toπ^{0}_{t}c$ and $ep\toγc\toπ^{\pm}_{t}b$ mediated by the anomalous top coupling $tcγ$. We find that the production cross section of the process $ep\toγc\toπ^{0}_{t}c$ is very small. With reasonable values of the parameters in TC2 models, the production cross section of the process $ep\toγc\toπ^{\pm}_{t}b$ can reach $ 1.2pb$. The charged top-pions $π^{\pm}_{t}$ might be directly observed via this process at the THERA collider based $γp$ collisions.
