Question: When exactly did the Higgs Field begin to exist (before cosmological inflation or after cosmological inflation)?

    $\begingroup$ All fields have presumably existed forever--they are part of the woodwork; how do you reckon otherwise? $\endgroup$ – Cosmas Zachos Jun 5 at 0:25
  • $\begingroup$ Are you asking when the electroweak symmetry breaking transition occurred (physics.stackexchange.com/a/392526)? $\endgroup$ – Chiral Anomaly Jun 5 at 1:30
  • $\begingroup$ after all, these are models. There are models where it is the Higgs field that generates inflation arxiv.org/abs/1307.0708 $\endgroup$ – anna v Jun 5 at 7:38
  • $\begingroup$ Dear anna v, dear Chiral Anomaly, dear Cosmas Zachos, dear Qmechanic. Thank you very much for your prompt responses. They are all VERY HELPFUL. I still need some time to digest. Are there any further comments? To be continued… $\endgroup$ – UNO Jun 5 at 16:56
  • $\begingroup$ a) 5.39 × 10 −44 sec: Planck-Time; b) 10 −43 sec: Grand Unified Theory (GUT)- Era; c.) 10 −35 sec: Beginning of Cosmological Inflation; d) between 10 −33 sec and 10 −30 sec: Ending of Cosmological Inflation; e) approx. 10 −10 sec: Higgs-Field/ breaking of symmetry triggers the Higgs mechanism $\endgroup$ – UNO Jun 8 at 6:27
