SUMMARY:Electroweak Symmetry Restoration at High Energies\, Theory Sem
 inar (High Energy/Cosmology)\, Tao Han\, University of Pittsburgh
DESCRIPTION:With the milestone discovery of the Higgs boson at the LHC
 \, detailed study of its properties becomes a high priority for collid
 er physics. After a brief overview of the properties of the longitudin
 al gauge bosons and the Higgs boson\, we revisit the Goldstone boson e
 quivalence theorem and define the “electroweak symmetry restorationâ
 €ť (EWSR) quantitatively. We present some examples to examine the EWSR
  via the processes with "radiation amplitude zeros” by separating ou
 t the gauge sector and the scalar sector. Finally\, we comment on what
  we learn from testing the EWSR and make some remarks on the SM at hig
 h energies in light of the UV completion. Event recording: https://you
