TL;DR Summary
Massive QED formalism.
I was reading Diagrammatica by Veltman and he treats the photon field as a massive vector boson in which gauge invariance is disappeared and the propagator has a different expression than in massless photon. After some googling, I found that this is one way to formulate QED which has the advantage of taking care of IR divergences. I would like to read more about the subject. What is the name of such formalism? is there any kind of QFT book (article, paper..) which explains it in detail? I saw some comments in Weinberg's book but Weinberg is too technical for me. Any sources would be appreciated.

or rather Stückelberg, who has shown that for the Abelian case you can have a gauge theory with massive gauge bosons.

Thanks! I was hoping to get an answer from you, as you always put me in the right direction. Do you also happen to know a reference that discusses this topic in detail rather than books only highlighting this mechanism?

If we release an electron around a positively charged sphere, the initial state of electron is a linear combination of Hydrogen-like states. According to quantum mechanics, evolution of time would not change this initial state because the potential is time independent. However, classically we expect the electron to collide with the sphere. So, it seems that the quantum and classics predict different behaviours!
