论文摘要
我们提出了一种半分析方法，用于计算由冰中任何风味的中微子引起的淋浴中相干的Askaryan辐射。我们将我们的结果与基于Zhaires代码的完整蒙特卡洛模拟的结果进行了比较。这种方法能够在任何实验相关的观察者位置在时间域中重现矢量电位，从而重现电场。这项工作扩展了发布的结果，仅对电子引起的淋浴有效。我们确定了由冰中中微子引起的所有类型的中微子诱导的淋浴所产生的无线电信号的半分析计算的有效性。该方法在计算上是有效的，仅需要输入淋浴的纵向电荷过剩曲线，并且在我们也提供的cherenkov角度，淋浴的远场区域中矢量电位的参数化。我们的方法避免了每当必须在给定的观察者位置计算无线电脉冲时，就会避免跟踪数百万个颗粒对电场的贡献。这些结果可以很容易地用于解释实验所采集的数据，以及基于ICE无线电技术的未来计划的计划和设计中。
We present a semi-analytical method for the calculation of coherent Askaryan radiation in showers induced by neutrinos of any flavor in ice. We compare our results with those of a full Monte Carlo simulation based on the ZHAireS code. This approach is able to reproduce the vector potential and hence electric field at any experimentally relevant observer position in the time domain. This work extends published results only valid for electron-induced showers. We establish the validity of the semi-analytical calculation of the radio signal produced by all types of neutrino-induced showers in ice. The method is computationally efficient and only requires as inputs the longitudinal charge excess profile of the showers and a parameterization of the vector potential in the far-field region of the shower at the Cherenkov angle that we also provide. Our methodology avoids tracking the contributions to the electric field from millions of particles every time the radio pulse has to be calculated at a given observer position. These results can be readily used in the interpretation of the data taken by experiments, and in the planning and design of future initiatives based on the radio technique in ice.
