Contribution

It provides a comparative analysis of monopoles and hybrids in Abelian projected lattice QCD, highlighting the influence of virtual fermions on hybrid densities.

Findings

Hybrid density exceeds monopole density.

Hybrid density is affected by virtual fermions.

Hybrid densities vary between quenched and non-quenched configurations.

Abstract

We study topological defects constructed from diagonal and non-diagonal gluons in Abelian projection of zero temperature lattice QCD. We compare results obtained in the quenched and non-quenched vacuum field configurations and show that the density of hybrids is higher than the density of monopoles. The density of some hybrids is sensitive to the presence of the virtual fermions.
