How exctly the higgs field originted after the big bang?

[Abersman]

i know that they are trying to recreate the higgs boson at CERN LHC, but talking about when the big bang happened, how was the higgs field suppose to happen?

 

[Drakkith]

I was under the impression that the higgs field always existed, and it was only once the energy levels of the universe were reduced below a certain point that things acquired mass.

The Higgs-particle field has a potential energy that's shaped like a bowl with a hump in the middle. When the temperature is high enough to make Higgs particles (T >~ m_H ~ 125 GeV), then the resulting Higgs-field fluctuations compensate for that central hump, and above about 300 GeV, make it disappear altogether.

That means that the Higgs field stops having a nonzero average value at about then, ending the low-energy Higgs mechanism.

The descriptions I've seen are similar to the prior post.
My understanding is the Higgs field are associated with particular types of vacuums. I have never heard it proposed that before the big bang there existed a Higgs field everywhere. Such a Higgs mechanism

involving different possible 'vacua' is..an essential ingredient of inflation

according to Roger Penrose in THE ROAD TO REALITY, 28.1.

I think the Higgs field is a manual input to inflation...and the standard model of particle physics...just like the inflation which originated with Guth is a manual input...a mathematical tool used to solve some issues and produce some observational predictions...I also checked several sections of Wikipeida...via "Higgs mechanism" and ended up here:

But if they describe the origin of the field I missed it: They say the Higgs boson is a tachyon...but not faster than light...

Tachyonic fields play a very important role in modern physics.

Perhaps the most famous example of a tachyon is the Higgs boson of the Standard model of particle physics. In its uncondensed phase, the Higgs field has a negative mass squared, and is therefore a tachyon.

The phenomenon of spontaneous symmetry breaking, which is closely related to tachyon condensation, plays a central part in many aspects of theoretical physics, including the Ginzburg–Landau and BCS theories of superconductivity.

Other examples include the inflaton field in certain models of cosmic inflation (such as new inflation[8][9]), and the tachyon of bosonic string theory

The link to http://en.wikipedia.org/wiki/Tachyon_condensation describes how a Higgs like scalar field produces particles...edit: here is a related discussion:
https://www.physicsforums.com/showthread.php?t=621236

and I am reminded from it that the Higgs field is associated with a non zero expectation vacuum...hence I believe that suggests the Higgs field did NOT exist before the BB...maybe an 'expert' will clarify for us.

The field that makes inflation is sometimes called the inflaton (no i), and it's like a spin-0 one.

However, the inflaton cannot be the Higgs particle, because of the great difference in energy scales:
Higgs: ~ 300 GeV
inflaton: ~ 10¹⁵ GeV
