$e^+e^-$对的切伦科夫辐射及其对$ν_e$诱导阵雨的影响
Cherenkov Radiation from $e^+e^-$ Pairs and Its Effect on $ν_e$ Induced Showers
摘要：
我们计算切伦科夫辐射的$e^+e^-$对在小的分离，发生后不久对转换。当粒子对间距小于发射光的波长时，辐射会减少（与两个独立粒子的辐射相比）。我们估计减少光在大型电磁阵雨，并讨论了探测器的影响，观察切伦科夫辐射阵雨在地球大气中，以及在海洋和南极冰。
英文摘要：
We calculate the Cherenkov radiation from an $e^+e^-$ pair at small separations, as occurs shortly after a pair conversion. The radiation is reduced (compared to that from two independent particles) when the pair separation is smaller than the wavelength of the emitted light. We estimate the reduction in light in large electromagnetic showers, and discuss the implications for detectors that observe Cherenkov radiation from showers in the Earth's atmosphere, as well as in oceans and Antarctic ice.
