摘要:

本文研究了在国际直线对撞机(ILC)上精确测量T宇称最小希格斯模型参数的可能性。该模型预测了新的规范玻色子(AH,ZH和WH),其中重光子(AH)是暗物质的候选者。这些新规范玻色子的质量强烈依赖于打破模型整体对称性的真空期望值。通过蒙特卡罗模拟的过程:e+ e- ->AH ZH和e+ e- -> WH+ WH-,我们表明如何精确地确定质量在ILC的模型的一个代表性的参数点。我们还讨论了小希格斯参数的测定及其对未来宇宙中暗物质遗迹热丰度测量的影响。

英文摘要:

We investigate a possibility of precision measurements for parameters of the Littlest Higgs model with T-parity at the International Linear Collider (ILC). The model predicts new gauge bosons (AH, ZH, and WH), among which the heavy photon (AH) is a candidate for dark matter. The masses of these new gauge bosons strongly depend on the vacuum expectation value that breaks a global symmetry of the model. Through Monte Carlo simulations of the processes: e+ e- ->AH ZH and e+ e- -> WH+ WH-, we show how precisely the masses can be determined at the ILC for a representative parameter point of the model. We also discuss the determination of the Little Higgs parameters and its impact on the future measurement of the thermal abundance of the dark matter relics in our universe.
