The correction of the littlest Higgs model to the Higgs production process $e^+e^-\to e^+e^-H$ at the ILC

Abstract

The littlest Higgs model is the most economical one among various little Higgs models. In the context of the littlest Higgs model, we study the process $e^{+}e^{-}\to e^{+}e^{-}H$ at the ILC and calculate the correction of the littlest Higgs model to the cross section of this process. The results show that, in the favorable parameter spaces preferred by the electroweak precision data, the value of the relative correction is in the range from a few percent to tens percent. In most case, the correction is large enough to reach the measurement precision of the ILC. Therefore, the correction of the littlest Higgs model to the process $e^{+}e^{-}\to e^{+}e^{-}H$ might be detected at the ILC which will give an ideal way to test the model.
