The way I read this: this method of finding non-pertrubative terms requires calculating perturbative terms first, that’s why it can’t be applied to QED and other more-or-less realistic theories. But of course string theorists can use this method to write more papers.
- evanb 4y agoPeople can calculate perturbative processes in QED. Some observables are known to 7 loops (!), last I paid attention.
- not2b 4y agoI'm much more interested in whether it can provide a better way to deal with the strong force. QCD is almost impossible to calculate with in most cases because everything diverges.
