论文摘要
我们重新考虑了由等离子体和$ν\barν$ -GAS组成的介质中电磁波（EM）波的折线问题的问题。由于违反了电子中微子 - 电子相互作用的均衡性，因此在这种培养基中产生了这种效果。我们最近对电子等离子体中光子极化算子校正的计算使我们能够显着改善对天体物理学中这种影响的一些先前估计。我们估计了在非偏见的血浆中传播的EM波的旋转能力，并与那里的遗物中微子和抗肿瘤的气体相互作用。我们表明，在存在等离子的情况下，在$ν\barν$ -gas中的EM波双折射效应在$ν\barν$ -GAS中的空白空间中所考虑的$ν\barν$ -gas显着超过了这种效果。这些以前的双折射治疗方法依赖于使用正向散射幅度$γν\ toγν$与Feynman图中的虚拟带电瘦小子一起使用的真空中壳光子的折射指数的计算。讨论了在实验中观察到的新效果的可能性。
We reconsider the problem of the birefringence of electromagnetic (EM) waves in a medium consisting of a plasma and a $ν\barν$-gas within the Standard Model of particle physics. The considered effect arises in such a medium due to the parity violation for the electroweak neutrino-electron interaction. Our recent calculations of the electroweak correction to the photon polarization operator in the electroweak plasma allow us to significantly improve some previous estimates of such effect in astrophysics. We estimate the rotary power for EM waves propagating in a non-relativistic plasma in the intergalactic space and interacting with the gas of relic neutrinos and antineutrinos there. We show that, in presence of a plasma, the EM wave birefringence effect in a $ν\barν$-gas exceeds significantly that effect in a $ν\barν$-gas in empty space considered earlier. These previous treatments of the birefringence relied on the calculations of the refraction index for on-shell photons in vacuum using the forward scattering amplitude $γν\to γν$ with virtual charged leptons in Feynman diagrams. The possibility to observe experimentally the new effect suggested here is discussed.
