In explicit symmetry breaking, the equations of motion of a physical system are variant under the broken symmetry; by contrast, for spontaneous symmetry breaking (SSB), these equations are invariant, but the entire system is not because its vacuum (background) is non-invariant. Further use for the SSB characteristic nonlinear realizations (Goldstone mode), and the group theoretical patterns involved.

Is it correct to discuss "Symmetry" and "Breaking of symmetry" on equal footing?
I think the questions in this post are "philosophy of science" material.

Origin of Mexican hat potential in Higgs mechanism
Without the Higgs mechanism, or some other effect like it, all bosons (a type of fundamental particle) would be massless, but measurements show that the W+, W−, and Z bosons actually have relativel …

What did electroweak symmetry breaking actually look like?
This has been sitting without an answer for some years, so I will describe how I see this cosmological phase transition.
I see it as similar to any phase transition: when water boils does it start w …
