The critical rate of fall-off coincides with that of the massless free scalar field theory. Related results and open problems are briefly discussed.

Nambu had shown how spontaneous breaking of a chiral symmetry could generate the masses of spin-½ particles, such as the proton and neutron, but his model predicted massless spin-0 particles (pions?), contrary to experimental …
WebGoldstone's theorem states that whenever a continuous symmetry is spontaneously broken, new massless (or light, if the symmetry was not exact) scalar particles appear in the spectrum of possible excitation. It was first formulated by Jeffrey Goldstone. WebIn functional analysis, a branch of mathematics, the Goldstine theorem, named after Herman Goldstine, is stated as follows: Goldstine theorem.
