强子反应和中微子衍射中中微子的长程关联II:中微子

Long-range correlations of neutrinos in hadron reactions and neutrino diffraction II: neutrino

Kenzo Ishikawa, Yutaka Tobita

摘要:

在这个II中,一个探测到高能π介子衰变中产生的中微子的概率被证明接受大的有限尺寸修正。中微子与物质的相互作用非常弱,与π介子和带电轻子一起用多体波函数描述。这个波函数慢慢地接近一个渐近形式,这是由中微子探测。整个过程由有限时间间隔的S矩阵描述,它与非守恒动能态耦合,相对论不变系统特有的宽谱的终态对半正定修正有贡献,类似于波通过孔的波的衍射。中微子的这种衍射成分在π介子能量变化的情况下变得长距离和稳定。此外,它有一个依赖于绝对中微子质量的普适形式。从而提出了一种测量中微子绝对质量的新方法。

英文摘要:

In this II, a probability to detect the neutrino produced in a high-energy pion decay is shown to receive the large finite-size correction. The neutrino interacts extremely weakly with matters and is described with a many-body wave function together with the pion and charged lepton. This wave function slowly approaches to an asymptotic form, which is probed by the neutrino. The whole process is described by an S-matrix of a finite-time interval, which couples with states of non-conserving kinetic energy, and the final states of a broad spectrum specific to a relativistic invariant system contribute to the positive semi-definite correction similar to diffraction of waves through a hole. This diffraction component for the neutrino becomes long range and stable under changes of the pion's energy. Moreover, it has a universal form that depends on the absolute neutrino mass. Thus a new method of measuring the absolute neutrino mass is suggested.
