# Are electroweak particles stable?

Photons that [are associated with] the electromagnetic force are stable; while the W and Z bosons that [are associated with] the weak force are short lived. I guess that the high temperate electroweak particles that combine the electromagnetic force and the weak force are stable like the photons; while the W and Z bosons with short lives appear only when needed for decay. Is anybody here familiar enough with the research of the electroweak particles to know if they are stable or not?

• Neither photons are made up of electromagnetic force nor the W/Z bosons are made of weak force . These statements are meaningless. Moreover, I haven't heard of anything like 'electroweak particles' while its true that high enough temperatures, before electroweak phase transition weak and electromagnetic forces were "unified" into a single electroweak force in a very precise sense. By 'electroweak particles' if you mean standard model particles then certainly all standard model particles are not stable (for example, muon, tau particle etc). – SRS Jun 25 '17 at 6:54
Above the electroweak transition neither photons nor the $W^\pm$ and $Z$ particles exist. Instead we get three gauge bosons, the $W_1$, $W_2$ and $W_3$ particles, associated with the $SU(2)$ symmetry and one gauge boson, the $B$ particle, associated with the $U(1)$ symmetry. All four particles are massless and are therefore stable like the photon.
