实验室实验中的对称暗能量

Symmetron dark energy in laboratory experiments

Amol Upadhye

摘要:

标量场是一种物质耦合的暗能量候选者,它通过对称性恢复有效地从高密度区域的物质中分离出来。我们考虑一个以前未探索的制度,其中的真空质量$μ\sim 2.4\times 10^{-3}$ eV的介子是附近的暗能量规模,和物质耦合参数$M \sim 1$ TeV是刚刚超过标准模型的能量。这样的场将在亚毫米距离上产生第五种力,可以通过短程引力实验来探测。我们表明,一个扭摆实验,如Eöt-Wash可以排除在此制度的所有自耦合$λ\lesssim 7.5$的电子。

英文摘要:

The symmetron scalar field is a matter-coupled dark energy candidate which effectively decouples from matter in high-density regions through a symmetry restoration. We consider a previously unexplored regime, in which the vacuum mass $μ\sim 2.4\times 10^{-3}$ eV of the symmetron is near the dark energy scale, and the matter coupling parameter $M \sim 1$ TeV is just beyond Standard Model energies. Such a field will give rise to a fifth force at submillimeter distances which can be probed by short-range gravity experiments. We show that a torsion pendulum experiment such as Eöt-Wash can exclude symmetrons in this regime for all self-couplings $λ\lesssim 7.5$.
