A Current Status of Electromagnetic Triviality

I know how to calculate the standard Landau pole result at one loop suggesting that a quantum field theoretic treatment of the electromagnetic force in the continuum is trivial.

I am wondering does this result continue to hold at higher loops, nonperturbatively or when electromagnetism is embedded in the electroweak force or the standard model. Or at least what is current thinking on the matter?

As a function of temperature the landau Pole in the context of the standard model is at higher energies beyond the Planck scale, in the case of QED . At zero temperature reverting back to the one loop bubble.

Where did you get the PDFs you attached? You should be giving links so we can check to be sure the PDFs are open access.

The second one is for sure not open access although there may be an illegal link where you can download it for free ;-)).
 
True. I've not seen that it is open access since I didn't realize the footnote.

So why then not quoting the official source instead of some medicre link?

The PDF link at semantic scholar goes to the arxiv preprint, which is open access.
