Singular pseudoparticles in Higgs theories
Abstract
We present a new class of pseudoparticles in four-dimensional Euclidean non-Abelian gauge theories with Higgs fields. These pseudoparticles, in the classical limit, have nonzero Lagrangian density at only one single point. We discuss the topological and analytic construction of these pseudoparticles and the related fractional-topological-charge configurations. The action of a unit-topological-charge pseudoparticle is the usual 8π2g2. These pseudoparticles are not field configurations, but are limiting cases of field configurations. Owing to quantum fluctuations, their size is proportional to ℏ if ℏ is small.
