衍射修正的中微子通量和$νN$总截面

Diffraction-corrected neutrino flux and $νN$ total cross section

Kenzo Ishikawa, Yutaka Tobita

摘要:

在粒子衰变中产生的中微子保持着一种不寻常的波动性质,在大的空间区域中显示出衍射现象。衍射为这一区域的中微子通量提供了一个新的分量,并改变了中微子实验中物理量的测定。本文研究了高能中微子核子散射的总截面。一个截面是成比例的夸克-部分子模型中的能量,并修改与能量相关的中微子通量引起的衍射分量。事件总数除以能量不是常数,而是具有轻微的能量依赖性。理论值与最近的实验符合得很好。

英文摘要:

A neutrino produced in a particle decay maintains an unusual wave nature that reveals a diffraction phenomenon in a large spatial region. Diffraction gives a new component to a neutrino flux in this region and modifies determinations of physical quantities in neutrino experiments. A total cross section of neutrino nucleon scattering at high energies is studied in this paper. A cross section is proportional to an energy in the quark-parton model and is modified with the energy-dependent neutrino flux induced by the diffraction component. A total number of events divided by the energy is not constant but has a slight energy dependence. Theoretical values agree well with the recent experiments.
