| Jul 25 at 21:11 | comment | added | Sanjana | What is the loophole in the argument where we apply (3) in 2 dimensions where the photon becomes massive due to loop corrections? | |
| Jul 18 at 12:54 | comment | added | Cosmas Zachos | @MKO ... but you can get there, through extra interactions, somehow . | |
| Jul 18 at 7:07 | comment | added | Prahar | The scalar field in $\phi^4$ theory is not a Goldstone boson. | |
| Jul 18 at 6:54 | comment | added | MKO | Thank you. What happens in $\phi^4$-theory? It has no symmetry $\phi\to \phi+a$. | |
| Jul 17 at 19:31 | comment | added | Cosmas Zachos | Pedantic nitpick on 1: It is possible to have SSB due to radiative corrections on a theory lacking it, so, then, it is the renormalized effective theory goldston that is massless. | |
