Abstract:
We consider the extended chiral group $E\chi$ and investigate whether
solitons–skyrmions can be formed by the chiral field with diquark parameters
in the symplectic subgroup of $E\chi$. We find that isolated solitons
{(}i.e., solitons in the gluonic vacuum{\rm)} can be stable in
the chromomagnetic vacuum and their topological charge starts from $\pm4/3$.
Keywords:
color chiral model, diquark, chiral anomaly.
