| 摘 要： | 希格斯(Higgs)粒子是迄今为止发现的第一个标量粒子.在粒子物理标准模型中,希格斯粒子起到了非常重要的作用.另一方面,在宇宙暴涨时期,使宇宙加速膨胀的往往是也一个标量场,或者标量粒子,被称为暴涨子.由于能标的不同,希格斯粒子不能直接作为暴涨子,但通过一些间接的手段,暴涨子却有可能是希格斯粒子在高能标时的另一种表现形式.本文作者回顾了希格斯暴涨模型,并且着重讨论了宇宙学常数在暴涨中所起到的作用.

| Abstract: | Higgs is the only scalar particle that already observed up to now. In the standard model of particle physics, Higgs plays a very important role. On the other hand,inflation is also driven by scalar field called inflaton. Higgs boson can not be the inflaton since the large hierarchy energy scale of the mass between inflaton and itself. However, by using some indirectly method, inflaton could be another aspect of the Higgs boson. In this paper,the authors review some Higgs inflation models and discuss the role of the cosmological constant during inflation. |
