发帖数: 1828 | 1 A sphaleron (Greek: σφαλερ "weak, dangerous") is a static (
time independent) solution to the electroweak field equations of the
Standard Model of particle physics, and it is involved in processes that
violate baryon and lepton number. Such processes cannot be represented by
Feynman diagrams, and are therefore called non-perturbative. Geometrically,
a sphaleron is simply a saddle point of the electroweak potential energy (in
the infinite dimensional field space), much like the saddle point of th |
