Description
In the Standard Model of Physics, the Higgs field is in a
broken phase at low temperature, and in a symmetric phase at high
temperature, with a second order transition in between. In this talk,
I consider a systematic expansion in N>>1 scalar field components to
access the non-perturbative properties of the PT-symmetric field
theory at low and high temperature. The results are qualitatively
different from the Standard Model and may have implications for our
understanding of how baryons have formed in our universe.
