物理真空是一个首选框架吗?

Is the physical vacuum a preferred frame ?

M. Consoli, E. Costanzo

摘要:

一般认为粒子物理学的物理真空应该用能量动量张量来表征,以保持精确的洛伦兹不变性。另一方面,如果基态的特征是它的能量-动量矢量,空间动量为零,能量不为零,那么真空将代表一个优选的框架。由于这两种理论方法都有自己的良好动机,我们提出了一个实验测试,以决定这两种情况。

英文摘要:

It is generally assumed that the physical vacuum of particle physics should be characterized by an energy momentum tensor in such a way to preserve exact Lorentz invariance. On the other hand, if the ground state were characterized by its energy-momentum vector, with zero spatial momentum and a non-zero energy, the vacuum would represent a preferred frame. Since both theoretical approaches have their own good motivations, we propose an experimental test to decide between the two scenarios.
