Non-Abelian dynamics in the resonant decay of the Higgs after inflation
  We study the resonant decay of the Higgs condensate into weak gauge bosons
after inflation and estimate the corrections arising from the non-Abelian
self-interactions of the gauge fields. We find that non-Abelian interaction
terms induce an effective mass which tends to shut down the resonance. For the
broad resonance relevant for the Standard Model Higgs the produced gauge
particles backreact on the dynamics of the Higgs condensate before the
non-Abelian terms grow large. The non-Abelian terms can however significantly
affect the final stages of the resonance after the backreaction. In the narrow
resonance regime, which may be important for extensions of the Standard Model,
the non-Abelian terms affect already the linear stage and terminate the
resonance before the Higgs condensate is affected by the backreaction of decay
products.
