My question is "What does the terminology 'charged under the gauge field' mean?" | |
Jul 11, 2017 at 12:15 | comment | added | ACuriousMind♦ | I'm not sure what exactly you expect as an answer here - yes, if you define "charged" as "transforms non-trivially under the gauge group", then the QED electric currents are uncharged. And yes, that definition clashes with our classical notion of calling $j^0$ the charge density. Asking whether certain terminology is "standard" is off-topic as primarily opinion-based - is there something else you want to know about this? | |
