质量和耦合常数的环境依赖性

Environmental Dependence of Masses and Coupling Constants

Keith A. Olive, Maxim Pospelov

摘要:

我们构造了一类与物质耦合的标量场模型,使得质量和耦合常数依赖于周围物质的密度。这种模型预测了地球上测得的耦合值与低密度天体物理环境中测得的耦合值之间的偏差,但不一定需要耦合常数随最近宇宙学过去的红移而演化。对Δα和Δ(m_p/m_e)作为周围物质密度的函数的实验室和天体物理实验是必要的。

英文摘要:

We construct a class of scalar field models coupled to matter that lead to the dependence of masses and coupling constants on the ambient matter density. Such models predict a deviation of couplings measured on the Earth from values determined in low-density astrophysical environments, but do not necessarily require the evolution of coupling constants with the redshift in the recent cosmological past. Additional laboratory and astrophysical tests of Δαand Δ(m_p/m_e) as functions of the ambient matter density are warranted.
