论文摘要
我们研究了中微子振荡的好奇特性的原因,将视为完全区分颗粒之间的干扰。这种效果的来源被确定为由量子场理论状态的许多粒子性质确定。首先强调的是,为了解释观察到的振荡,状态的中微子子空间不应被解释为三个中微子Fock空间的直接乘积,这相当于施加超选择规则。此外,有人认为,这种直接乘积空间的线性完成允许描述所测量的振荡。因此,应将标准模型状态(SM)状态的空间解释为与可区分粒子相关的所有Fock空间(玻色子或费米)的直接乘积的线性完成。然后,因此,中微子振荡被确定为独立颗粒之间的干扰,这是由于状态在中微子Fock空间的直接乘积之外产生的。这种解释似乎意味着粒子中可区分的颗粒以及凝结物理物理学中的可区分颗粒之间进行了大量干扰。为了寻求清晰,讨论是在两个相对论自由大规模中微子的简单量子场理论(QFT)模型的框架内进行的。
We investigate the causes of the curious property of neutrino oscillations of looking as an interference between fully distinguishable particles. The sources of this effect are identified as to be determined by the many particle nature of space of states of the quantum field theory. It is firstly underlined that in order to explain the observed oscillations, the neutrino subspace of states should not be interpreted as the direct product of the three neutrinos Fock spaces, which is equivalent to imposing a superselection rule. Further, it is argued that the linear completion of such a direct product space of states permits to describe the measured oscillations. Thus, the space of states of te Standard Model (SM) should be interpreted as the linear completion of the direct product of all the Fock spaces (boson or fermions ones) associated to the distinguishable particles. Then, it follows that the neutrino oscillations are determined as interference between independent particles, which are generated by states being outside the direct product of the neutrino Fock spaces. This interpretation seems to imply a large amount of interference observations between distinguishable particles in Particle as well as in Condensed Matter Physics. For seeking clearness, the discussion is done in the framework of a simple Quantum Field Theory (QFT) model of two relativistic free massive neutrinos.
