This is a question that I have tried to pose several times without any success but, anyway, I would like to try again for the very last time. Asume for a moment that EW-SSB (electroweak spontaneous symmetry breaking) actually happened in our early universe. Imagine that our Standard Model of particle physics is the way it is NOW just because the temperature dropped below a critical value. I ASSUME (and I may very well be wrong) that, above this temperature (critical T), in an earlier universe, the relevant charges should be the weak isospin, the weak hipercharge and color. I also think that the isospinor VEV should be 0 and, therefore, all leptons, quarks and interaction bosons should be massless. I also ASSUME that we can can make quantitative predictions using the more symmetric model of particle physics at temperatures just above critical T (just before the EW-SSB phase transition took place), although I am much less confident about this assumption. I would be very grateful if someone could help me.
