电动力学与红外标度和PVLAS实验
Electrodynamics with an Infrared Scale and PVLAS experiment
摘要：
我们考虑一个红外洛伦兹破坏与最近的结果PVLAS实验。我们的分析是基于一个关系，可以建立，在一定条件下，轴向粒子理论和电动力学与红外尺度。在PVLAS情况下，该条件意味着两个色散关系，使得红外尺度$|\vec θ|$、逆轴子-光子耦合常数$M^{-1}$和外磁场${\vec B}$可以通过公式$|{\vec θ}|= {|\vec B|}/M$连接。我们的分析，这只需要一个非动力学的（非对称的）轴向类场导致$|{\vecθ}| \leq 5.4 \times 10^{-7}$ meV和$M^{-1} \sim 1.2 \times 10^{-3}$ GeV $^{-1}$。
英文摘要：
We consider an infrared Lorentz violation in connection with recent results of PVLAS experiment. Our analysis is based in a relation that can be established, under certain conditions, between an axial-like-particle theory and electrodynamics with an infrared scale. In the PVLAS case, the conditions imply two dispersion relations such that the infrared scale $|\vec θ|$, the inverse axion-photon coupling constant $M^{-1}$ and the external magnetic field ${\vec B}$ can be connected through the formula $|{\vec θ}|= {|\vec B|}/M$. Our analysis, which only requires a non-dynamical (auxiliar) axial-like field leads to $|{\vecθ}| \leq 5.4 \times 10^{-7}$ meV and $M^{-1} \sim 1.2 \times 10^{-3}$ GeV $^{-1}$.
