Thank you again for your comments. It helps a lot.

comment Semileptonic decays of the $B_c$ meson
Thank you very much! Is it possible to introduce something like parton distribution function to relate the tree-level approximation to the decay of $B_c$ meson?

comment Derivation of neutrino oscillation phase factor
From the PDG Review provided by user12262, I found another article Quantum Theory of Neutrino Oscillations for Pedestrians - Simple Answers to Confusing Questions which is instructive on this question.

comment Derivation of neutrino oscillation phase factor
Thank you very much. From the PDG, the time interval $T$ can be related by $T=L/\bar{v}$, where $\bar{v}$ is the ''average'' velocity. But why it cannot be treated as constant?

comment Evaluate $1$-loop contribution to the $4$-point Green's function
The $\int_0^1d x$ is copyed from (2). The two $I$s are not the same in your comments.

comment Evaluate $1$-loop contribution to the $4$-point Green's function
For $m^2=0$, (3) can be expressed by the Euler integral.

comment Evaluate $1$-loop contribution to the $4$-point Green's function
We cannot obtain an analytical expression of the integral (3). For $d=4$, (1) is log divergent.

comment Evaluate $1$-loop contribution to the $4$-point Green's function
And $\Delta=q_{\mathrm{E}}^2x(1-x)+m^2$, it is independent of $p_{\mathrm{E}}$.
