从μ子到高能轻子

High energy leptons from muons in transit

Alexander Bulmahn, Mary Hall Reno

摘要:

数值计算了μ子在输运过程中产生轻子对的电子和τ的能量分布。我们使用微分截面来计算地下轻子通量从入射大气μ子通量,考虑传统和提示通量的贡献。本文给出了带电电流微分中微子截面的一个近似形式,并用于计算由大气中微子产生单轻子。我们比较了由入射μ子产生的地下轻子通量与由入射中微子和μ子韧致辐射光子产生的地下轻子通量。我们讨论了它们与地下探测器的相关性。

英文摘要:

The differential energy distribution for electrons and taus produced from lepton pair production from muons in transit through materials is numerically evaluated. We use the differential cross section to calculate underground lepton fluxes from an incident atmospheric muon flux, considering contributions from both conventional and prompt fluxes. An approximate form for the charged current differential neutrino cross section is provided and used to calculate single lepton production from atmospheric neutrinos. We compare the fluxes of underground leptons produced from incident muons with those produced from incident neutrinos and photons from muon bremsstrahlung. We discuss their relevance for underground detectors.
