Abstract

We investigate a possibility to measure parameters of the Littlest Higgs model with T-parity at the ILC with √s = 500 GeV. The model predicts new gauge bosons (AH, ZH, and WH), among which the heavy photon (AH) is a candidate for dark matter. Through Monte Carlo simulations of the process of e ⁺e^- → A_HZ_H, we show that the masses can be determined with accuracies of 16.2% for mA_H and 4.3% for mZ_H. In additionally, the vacuum expectation value can be determined with accuracies of 4.3%.
