真空能与标准模型物理

Vacuum Energy and Standard Model Physics

摘要:

本文研究了标准模型(SM)场对真空能量(包括紫外发散能量和有限能量)的单圈贡献的消除条件。事实证明,这是不可能的,除非除了几个玻色子,至少有一个质量在特定范围内的大质量费米子。在检查一个最简单的SM扩展满足的限制,人们发现,最轻的大质量玻色子的质量范围与目前的希格斯质量边界兼容。我们不考虑与凝聚或重整化群运行有关的效应。

英文摘要:

The conditions for the cancellation of one loop contributions to vacuum energy (both U.V. divergent and finite) coming from the Standard Model (SM) fields are examined. It is proven that this is not possible unless one introduces besides several bosons, at least one massive fermion having mass within specific ranges. On examining one of the simplest SM extensions satisfying the constraints one finds that the mass range of the lightest massive boson is compatible with the present Higgs mass bounds. We do not consider effects associated with condensates or renormalization group running.
