| Jul 5, 2022 at 14:24 | comment | added | anna v | @Stevex "say fields interact (couple) with different strengths. " It is not an interaction in the usual QFT definition of interactions. Remember the Higgs mechanism . "The simplest description of the mechanism adds a quantum field (the Higgs field) that permeates all Hilbert spaces of the Standard Model. Below some extremely high temperature, the field causes spontaneous symmetry breaking during interactions.The breaking of symmetry triggers the Higgs mechanism, causing the bosons it interacts with to have mass.

| Jul 5, 2022 at 12:02 | comment | added | Miyase | How do you define mass in the context of a theory that has no gravitational interaction? I'm not sure the distinction between mass and intertia is relevent here. In QFT, mass is defined as a pole in the free propagator of a field, and it happens to coincide with the usual mass (after renormalization). | |
| Jul 5, 2022 at 12:00 | comment | added | Stevex | Rather than using "syrup", why not just say fields interact (couple) with different strengths. This would also explain dark matter. Normal matter couples with both electromagnetic and Higgs fields. Dark matter only couples with the Higgs field. Also, is there anything wrong in saying the Higgs mechanism appears to give particles inertia rather than mass directly? | |
| Jul 5, 2022 at 11:54 | comment | added | Miyase | Honestly, I'm not sure this is relevant in the context of QFT. I've never seen the term "inertia" used there, and if I saw it I'd understand it as completely identical to mass. | |
