论文摘要
考虑到真空极化和光子后坐力，分析了极力磁场中的超级电荷粒子的光子发射。真空极化是通过折射率在现象学上进行处理的。光子发射发生在协同（合作）同步基因 - 切伦科夫工艺中[J. Schwinger，W。Tsai和T. Erber，《物理年鉴》，96 303（1976）]，与同步加速器发射相似，而不是与Cherenkov One。对于电子，即使超出了非扰动量子电动力学的可能发作（QED），真空极化对发射光谱的影响也不明显。但是，真空极化对发射光谱的影响可以观察到已经以$γb / b_s \约30 $的us量观察到，而$γ$ the muon lorentz因子，$ b $磁场强度和$ b_s $ $ b_s $。然而，真空极化仅导致辐射谱的最大值增强10％。
The photon emission by an ultrarelativistic charged particle in extremely strong magnetic field is analyzed, with vacuum polarization and photon recoil taken into account. The vacuum polarization is treated phenomenologically via refractive index. The photon emission occurs in the synergic (cooperative) synchrotron-Cherenkov process [J. Schwinger, W. Tsai and T. Erber, Annals of Physics, 96 303 (1976)] which is similar to the synchrotron emission rather than to the Cherenkov one. For electrons, the effect of the vacuum polarization on the emission spectrum is not evident even beyond the probable onset of non-perturbative quantum electrodynamics (QED). However, the effect of the vacuum polarization on the emission spectrum can be observable for muons already at $γB / B_S \approx 30$, with $γ$ the muon Lorentz factor, $B$ the magnetic field strength and $B_S$ the critical QED field. Nevertheless, vacuum polarization leads to only 10% enhancement of the maximum of the radiation spectrum.
