光速与光子质量研究的新进展

The New Process of the Study on Light Velocity and Photon Mass

摘要: 基于量子电动力学中的长波光子和频率最小值理论，并应用光子质量范围的观测结果，对于光子质量与光速之间的关系，近年来有了新的理论探索。光速的最低值υ_min近似地也是一个常数, 仅低于极限速度c大约10%。由光子质量引起的真空中光速的色散，即光速由υ_min到c的全部变化，只会发生在频率最小值附近很小的频率区间之内，换言之，只有长波光子的速度在真空中是色散的。另一方面，对于常用的频率而言，光速总是精确地等于极限值c，没有色散，所以，麦克斯韦方程适用，电磁场保持规范不变性，从而掩盖了光子的质量。本文还对如何寻找长波光子给出了建议。

Abstract: Based on the theories of long wavelength photons and minimum frequency in quantum electro-dynamics and on the experimental limits of photon mass, the relationship between photon mass and the light velocity has been theoretically explored in recent years. The lowest light velocity υ_min is approximately a constant about 10% lower than the limiting velocity c. The vacuum dispersion caused by photon mass, namely the total change of the light velocity from υ_min to c, takes place within only a small frequency region nearby the minimum frequency, in other words, only the velocity of the long wavelength photons is dispersed in vacuum. On the other hand, the light velocity with the frequency in common use is always accurately equal to the limiting velocity c without dispersion, therefore Maxwell equations are practically applicable, and the electromagnetic field keeps gauge invariance property so that the photon mass is concealed. A suggestion for how to seek the long wavelength photons is put forward in the paper.
