μ介子输运中轻子对产生的截面和能量损失

Cross sections and energy loss for lepton pair production in muon transport

A. Bulmahn, M. H. Reno

摘要:

我们重新评估电子-正电子对生产的电磁相互作用的μ子在通过材料。我们的方法,通过使用非弹性和弹性散射的结构函数,包括强子反冲,使形式主义有用的tau对生产在高能量。我们的电子-正电子对产生的结果与先前的评估一致。Tau对的产生,除了通常的与原子核的相干散射和与原子电子的散射之外,还具有来自非弹性散射的显著贡献。

英文摘要:

We reevaluate electron-positron pair production from electromagnetic interactions of muons in transit through materials. Our approach, through the use of structure functions for inelastic and elastic scattering and including hadronic recoil, make the formalism useful for tau pair production at high energies. Our results for electron-positron pair production agree well with prior evaluations. Tau pair production, has a significant contribution from inelastic scattering in addition to the usual coherent scattering with the nucleus and scattering with atomic electrons.
