This question is in regards to the electroweak force itself before its symmetry is broken into the weak and electromagnetic force. Lets say hypothetically that the ambient temperature of the universe or of a certain volume of space was hot enough to restore the electroweak symmetry like it was during the electroweak epoch. What are the actual bosons that would mediate this force in this environment. I mean clearly the photon, Z, W+, and W- bosons wouldn't exist right? I read somewhere about a B boson and three other W bosons labeled W1, W2, and W3. Would those be the actual bosons mediating the electroweak force under such conditions or are they merely a mathematical figment. If they do have a tangible existence, are those three W bosons unique from each other or are they the exact same thing labeled to show that three come out of the math?
