论文摘要
光子是无质量粒子的范例，当前的实验测试在其质量上设置了严重的上限。在实验室尺度上，探测如此小的质量或等效的大康普顿波长是挑战的，但是行星或天体物理现象可能会达到更好的敏感性。在这项工作中，我们考虑了有限光子质量对地球层腔中舒曼共振的影响，因为循环地球的TM模式具有$ \ Mathcal {o}的特征性频率（10 \，{\ rm hz}）$，可能对$m_γ\ \ y \ y of $m_γ\ rm \ rm \ rm \ rm \ rm \ rm for EV/C}^2 $。特别是，我们更新kroll [phys的限制。莱特牧师。 27，340（1971）]，$m_γ\ leq 2.4 \ times 10^{ - 13} \，{\ rm ev/c}^2 $，通过考虑大气的现实电导率曲线。我们发现保守的上限$m_γ\ leq 2.5 \ times 10^{ - 14} \，{\ rm ev/c}^2 $，比kroll的早期投影更严格。
The photon is the paradigm for a massless particle and current experimental tests set severe upper bounds on its mass. Probing such a small mass, or equivalently large Compton wavelength, is challenging at laboratory scales, but planetary or astrophysical phenomena may potentially reach much better sensitivities. In this work we consider the effect of a finite photon mass on Schumann resonances in the Earth-ionosphere cavity, since the TM modes circulating Earth have eigen-frequencies of order $\mathcal{O} (10 \, {\rm Hz})$ that could be sensitive to $m_γ\approx 10^{-14} \, {\rm eV/c}^2$. In particular, we update the limit from Kroll [Phys. Rev. Lett. 27, 340 (1971)], $m_γ\leq 2.4 \times 10^{-13} \, {\rm eV/c}^2$, by considering realistic conductivity profiles for the atmosphere. We find the conservative upper bound $m_γ\leq 2.5 \times 10^{-14} \, {\rm eV/c}^2$, a factor 9.6 more strict than Kroll's earlier projection.
