具有可忽略Lorentz不变性破坏的标准模型过程的大质量中微子程序

Procedure with Massive Neutrinos for the Standard Model Processes with Negligible Lorentz Invariance Violation

Josip Soln

摘要:

对于电弱相互作用,在有质量中微子Fock空间中发展了有质量中微子微扰运动学过程,微扰展开参数是中微子质量与能量的比值。这个程序,与Pontecorvo-Maki-nakagawa-Sakata修改的电弱拉格朗日,计算的横截面与新的中微子能量投影算符在大质量中微子福克空间,导致在标准模型质量较少的味道中微子横截面,加上洛伦兹非不变的中微子振荡横截面,这是正比于中微子质量的平方,因此,在实验室中,实际上是不可观察的。这个方案强化了这样一个概念,即质量较小的味中微子可以被认为是三个大质量中微子的叠加。

英文摘要:

For the electroweak interactions, the massive neutrino perturbative kinematical procedure is developed in the massive neutrino Fock space; The perturbation expansion parameter is the ratio of the neutrino mass to its energy. This procedure, with the Pontecorvo-Maki-nakagawa-Sakata modified electroweak Lagrangian, calculates the cross-sections with the new neutrino energy projection operators in the massive neutrino Fock space, resulting in the Standard Model mass-less flavor neutrino cross-sections, plus the Lorentz non-invariant neutrino oscillation cross-sections which are proportional to the squares of neutrino masses and, as such, practically unobservable in the laboratory. This scheme reinforces the notion that the mass-less flavor neutrino can be considered as the superposition of three massive neutrinos.
