论文摘要
基于应用于中微子的开放系统的量子场理论的一个新的理论框架已开发出来，以描述外部环境中的中微子进化，这些进化涉及中微子量子解的影响。开发的新方法使人们能够获得解释中微子参与的特定过程的变质和放松参数的明确表达，以及外部环境和中微子本身（包括中微子能量）的特征。我们已经使用这种方法来考虑由天体物理环境中中微子辐射衰减对光子和深色光子的中微子量子反应的新机制。即将推出的新大容量中微子探测器的前景强调了进行研究的重要性，这些中微子探测器将在超级新星的中微子通量的高统计量测量中提供新的边界。
A new theoretical framework, based on the quantum field theory of open systems applied to neutrinos, has been developed to describe the neutrino evolution in external environments accounting for the effect of the neutrino quantum decoherence. The developed new approach enables one to obtain the explicit expressions of the decoherence and relaxation parameters that account for a particular process, in which the neutrino participates, and also for the characteristics of an external environment and of the neutrino itself, including the neutrino energy. We have used this approach to consider a new mechanism of the neutrino quantum decoherence engendered by the neutrino radiative decay to photons and dark photons in an astrophysical environment. The importance of the performed studies is highlighted by the prospects of the forthcoming new large volume neutrino detectors that will provide new frontier in high-statistics measurements of neutrino fluxes from supernovae.
