ABSTRACT: We consider the extended chiral group Eχ and investigate whether solitons-skyrmions can be formed by the chiral field with diquark parameters in the symplectic subgroup
of Eχ. We find that isolated solitons (i.e., solitons in the gluonic vacuum) can be stable in the chromomagnetic vacuum and their
topological charge starts from ±4/3.

ABSTRACT: We study a model of the color skyrmion in the vacuum field in the framework of the color group SU(3) and one flavor in the four-dimensional space. We obtain the static mass functional and variational equations, determine the asymptotic behavior, and evaluate the interskyrmion potential for the case of the spherically symmetric skyrmion configuration.

ABSTRACT: We review the induced-gravity approach according to which the Einstein gravity is a long-wavelength effect induced by underlying fundamental quantum fields due to the dynamical-scale symmetry breaking. It is shown that no ambiguities arise in the definition of the induced Newton and cosmological constants if one works with the path integral for fundamental fields in the low-scale region. The main accent is on a specification of the path integral which enables us to utilize the unitarity condition and thereby avoid ambiguities. Induced Einstein equations appear from the symmetry condition that the path integral of fundamental fields for a slowly varying metric is invariant under the local GL(4, R)-transformations of a tetrad, which contain the local Euclidean Lorentz, O(4)-rotations as a subgroup. The relationship to induced quantum gravity is briefly outlined.

ABSTRACT: A chiral Lagrangian for massive pseudoscalar mesons is derived from the QCD-generating functional by the chiral bosonization method. The low energy region in the fermionic integral where chiral noninvariant quark fluctuations dominate, is described by two mass parameters — an invariant cutoff and a spectral asymmetry M related to the gluon and quark condensates.
