摘要：
Numerical simulations of the bosonic sector of the SU(2) x U(1) electroweak standard model in 3 + 1 dimensions have demonstrated 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. It contains total energy roughly 30 TeV localized in a region of radius 0.05 fm. A detailed description of these numerical results is presented.
