Current Status of Electromagnetic Triviality

[Son Goku]

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.

The second one is for sure not open access although there may be an illegal link where you can download it for free ;-)).

The second one for sure is open access. Click "View PDF" at the journal page and read the footnote at the first page of pdf. https://www.sciencedirect.com/science/article/pii/S0370269315004165?via=ihub

 

[vanhees71]

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.
