论文摘要
我们提出了一个构想，即对带电的Lepton和Virtual W-Boson的散射，$L_β +W_ρ\ rightArrowl_α +W_λ$的散射，使用所有涉及所有涉及的平面波的相对性中微子的传统pontecorvo振动符。在路径积分的图像中，中微子在生产和检测顶点之间的时间向前传播，它们分别在3维间距类型的超丘面上被限制在宏观正面的正面时间$τ$上。如果一个人总和$τ$的所有可能值（包括负$τ$），则将正式回收协变量的Feynman振幅。
We propose an idea of the constrained Feynman amplitude for the scattering of the charged lepton and the virtual W-boson, $l_β + W_ρ \rightarrow l_α + W_λ$, from which the conventional Pontecorvo oscillation formula of relativistic neutrinos is readily obtained using plane waves for all the particles involved. In a path integral picture, the neutrino propagates forward in time between the production and detection vertices, which are constrained respectively on the 3-dimensional spacelike hypersurfaces separated by a macroscopic positive time $τ$. The covariant Feynman amplitude is formally recovered if one sums over all possible values of $τ$ (including negative $τ$).
