A simple scattering problem is analyzed where coupling between constituents does not cause catastrophes. It is proposed to build QFT in the same manner.

Comments

1. I claim the authorship.

2. As a short summary I propose the following text: "I analyze a simple scattering problem where coupling between constituents does not cause catastrophes. I propose to build QFT in the same manner."

3. You are not obliged to give a review when you downvote an article in the Review section, but short indications what is wrong in the article would help the science.

I updated the article, mainly with adding an Appendix about mixed variables to show that guessing the right Hamiltonian is important and its splitting matters.

It's been published on-line in "Physics Journal".
