inconsistency of QED

[steg]

The existence of the Landau pole is pretty good evidence of the
inconsistency of QED. Now, it's possible, I suppose, that there is
actually some nonperturbative UV fixed point for QED that we can't see
right now, but I don't think it's likely.

Nonetheless, the infinities that show up in individual diagrams aren't a
big deal. The infinities that show up in RG flows indicate that the
theory is effective. None of this is a mystery and hasn't been for years.

Hey Lev, does a question exist anywhere in those two paragraphs? Or did it disappear up its own singularity?

Renormalization isn't an issue and hasn't been for years. The answer is
that QED is an effective theory with an explicit cutoff. One needs to
embed it in some well defined UV completion to get a complete theory.
I don't think anyone proved that this is necessary.

I don't think you understood what this website is for.

Firstly, to elicit deffinitive, knowledgeable responses that can be utilized by the questioner to arrive at enlightenment, one must have a de minimus comprehension of the subject.  I would also suggest that cutting and pasting would serve you better if editing were accomplished prior to clicking "submit"... in my humble opinion... Now, if you'd like to discuss the properties of muons as they relate to QED...
