论文摘要
粒子振荡（尤其是中微子）振荡中相干性的量子场理论描述是粒子物理学中的常规问题。在本次演讲中，将解释粒子振荡的标准方法的几种矛盾之处，以及如何通过一种受Bardeen-cooper-schrieffer超导性和NAMBU的新方法启发的新方法来解释它们。形式主义导致对最初由Pontecorvo和Gribov撰写的中微子振荡概率进行校正，但是在超层流性的中微子极限中验证了标准概率。大规模的中微子状态被解释为无质质风味中微子的“库珀对”真空凝结物上的准粒子。新定义的振荡粒子状态是用于中微子振荡的，klauder-sudarshan-glauber cooherent状态用于量子光学。
The quantum field theoretical description of coherence in the oscillations of particles, especially neutrinos, is a standing problem in particle physics. In this talk, several inconsistencies of the standard approach to particle oscillations will be explained, and how they are resolved in a process-independent manner, by a novel approach inspired by the Bardeen--Cooper--Schrieffer theory of superconductivity and the Nambu--Jona-Lasinio model. The formalism leads to corrections to the neutrino oscillation probability originally written by Pontecorvo and Gribov, however the standard probability is validated in the ultrarelativistic neutrino limit. The massive neutrino states are interpreted as quasiparticles on a vacuum condensate of "Cooper pairs" of massless flavour neutrinos. The newly defined oscillating particle states are for neutrino oscillations what the Klauder--Sudarshan--Glauber coherent states are for quantum optics.
