An electroweak oscillon.
A numerical simulation of the full bosonic sector of the SU(2)xU(1) electroweak standard model in 3+1 dimensions demonstrates the existence of an oscillon--an extremely long-lived, localized, oscillatory solution to the equations of motion--when the Higgs mass is equal to twice the W+/- boson mass. The oscillon contains total energy 6 TeV [corrected] localized in a region of radius 0.05 fm.
