The aim of the proposal is the more exact calculation of the energy loss processes of high-energy muons. The energy loss processes are the foundation of energy reconstruction for high-energy muons in neutrino telescopes such as IceCube, ANTARES or KM3NeT. In particular the calculation of diffractive and radiative corrections to the dominant process, the electron-positron pair production by high-energy muons, is a central aim of this proposal. This is intended to decrease the systematic uncertainties on the energy reconstruction.

该提案的目的是更精确地计算高能μ子的能量损失过程。在IceCube、ANTARES和KM 3 NeT等中微子望远镜中，能量损失过程是高能μ子能量重建的基础。特别是计算衍射和辐射校正的主导过程，电子-正电子对生产的高能μ子，是这个建议的一个中心目标。这是为了减少能源重建的系统不确定性。
