Simulation study of ZHAH mode in Littlest Higgs Model with T-Parity
Abstract
We investigate a possibility to measure parameters of the Littlest Higgs model with T-parity at the ILC with sqrt(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- -> AH ZH, we show that the masses can be determined with accuracies of 16.2% for mAH and 4.3% for mZH. In additionally, the vacuum expectation value can be determined with accuracies of 4.3%.
