Electroweak unification is discussed in the Big Bang model and variant proposals, and there is a transition at energies of 100 GeV where the EW symmetry is unbroken and a quark gluon plasma phase dominates.
In my answer to the question
the relevant plots for this question can be found and links for the progress of phenomenology up to now.
It was not possible to find any reference to electroweak symmetry breaking in the models proposed to fit the LHC experiments plasma data, even though the claim is that the quark gluon plasma studies the early stages of the universe.
In this proposal for the proposed future FCC collider I found that even for its high energies the mean energy density is less than the 100 GeV seen in the Big Bang histories, it will be of order 40GeV, while LHC plasmas are of order 20GeV energy density.
The phase diagram which includes quark gluon plasma explains this , quark gluon plasma is necessary but not sufficient for electroweak symmetry to be restored.
BUT the lab experiments are nucleus on nucleus, individual measurements. As it is a quantum phenomenon, there should be the tail of phase space at high energies which would have higher energy densities, even to 100 GeV , considering the TeV available at LHC. Those specific interactions should have crossed the 100 GeV , and the symmetry should be restored.
This means among other things that all quarks produced will have zero mass. As a consequence the probability of getting flavor particle antiparticle pairs should be equal. For example a top-antitop would have the same probability to be created as a bottom anti-bottom or as charm anti-charm in the final jet output from the plasma.
There have been differences found in various production rates, but nowhere did I find a hint that restoration of electroweak symmetry could be contributing to this in the phenomenological models used.
My question is: am I wrong? because I did not go into the models carefully?
Is the contribution of restoration of electroweak symmetry in the tails of distributions taken into account in the quark gluon plasma phenomenology for LHC energies, and it is not statistically expected to be detectable?
Edit in may 2020:
There is this phenomenology paper that has done calculations :
We compute the leading-order evolution of parton distribution functions for all the Standard Model fermions and bosons up to energy scales far above the electroweak scale, where electroweak symmetry is restored. Our results include the 52 PDFs of the unpolarized proton, evolving according to the SU(3), SU(2), U(1), mixed SU(2) x U(1) and Yukawa interactions. We illustrate the numerical effects on parton distributions at large energies, and show that this can lead to important corrections to parton luminosities at a future 100 TeV collider.
