作为暗能量来源的希格斯锯机制

A Higgs--Saw Mechanism as a Source for Dark Energy

Lawrence M. Krauss, James B. Dent

摘要:

由中微子自然产生小中微子质量的跷跷板机制的动机,我们探讨如何一个小的GUT尺度之间的混合标准模型希格斯粒子和一个无质量的隐藏扇区标量可以自然地产生一个小的质量和VEV的新标量产生一个假真空能量密度的贡献相比,所观察到的暗能量主导目前的宇宙膨胀。新的标量在现有的地球实验中没有产生可辨别的特征,因此人们可能不得不依赖于这个想法的其他宇宙学测试。

英文摘要:

Motivated by the see-saw mechanism for neutrinos which naturally generates small neutrino masses, we explore how a small GUT-scale mixing between the Standard Model Higgs and an otherwise massless hidden sector scalar can naturally generate a small mass and VEV for the new scalar which produces a false vacuum energy density contribution comparable to that of the observed dark energy dominating the current expansion of the Universe. The new scalar produces no discernible signatures in existing terrestrial experiments so that one may have to rely on other cosmological tests of this idea.
