Abstract We attempt the derivation of a new coupling function between ground level and primary cosmic rays for the case of Forbush decreases. The calculations for the new function are based on basic Quantum Field Theory theoretical tools, something that has not been attempted till now in other widely used cosmic ray coupling functions. The use of Quantum Field Theory calculations in cosmic rays events in general, is expected to be a suitable frame of work since it describes well the high energy particle interactions which result in variations to the total number of the particles involved through annihilation or creation of particles. The newly computed function is tested to the case of two events of Forbush decreases, February 2011 and March 2012, using data from the high resolution neutron monitor database. Results for the primary particle intensity values obtained from this function are compared directly to the corresponding ones from the use of the Dorman's widely accepted coupling function. The two sets are discussed in detail in order to deduce the possible suitability of Quantum Field Theory tools to cosmic ray events.

一个新的近似耦合函数：Forbush 的案例递减

摘要 我们尝试在 Forbush 减小的情况下推导地平面和初级宇宙射线之间的新耦合函数。新函数的计算基于基本的量子场论理论工具，这是迄今为止在其他广泛使用的宇宙射线耦合函数中尚未尝试过的。在宇宙射线事件中使用量子场论计算通常被认为是一个合适的工作框架，因为它很好地描述了高能粒子相互作用，这些相互作用导致通过粒子湮灭或创造所涉及的粒子总数发生变化. 使用高分辨率中子监测数据库中的数据，新计算的函数在 2011 年 2 月和 2012 年 3 月这两个 Forbush 下降事件的情况下进行了测试。从该函数获得的初级粒子强度值的结果直接与使用 Dorman 广泛接受的耦合函数的相应结果进行比较。详细讨论这两组是为了推断量子场论工具对宇宙射线事件的可能适用性。
