Unitarity of superfluid states in nuclear matter is studied in the case that the quasi-particle energy matrix holds scalar and vector components in isospin space at the same time, ξ = ξ0 + ξτ. The vector component of ξ can ...

Basic features of Lagrangian formulation for AdS₄ x CP³ superstring in the framework of OSp(4|6)/(SO(1,3) x U(3)) sigma-model approach are reviewed with the emphasis on realization osp(4|6) background isometry superalgebra ...

The long-standing problem of a divergent behaviour of the Aharonov-Bohm scattering amplitude in the forward direction is reconsidered. We show that this divergence has no physical consequences, being an artefact of the ...

The fully differential angular distribution for the rare flavor-changing neutral current decay Bd⁰ → K*⁰( → K⁻π⁺)e⁺e⁻ is studied. The emphasis is placed on accurate treatment of the contribution from the processes Bd⁰ → ...

It is shown that the regimes with chaotic motion are also inherent in dynamic systems having only one degree of freedom. Such opportunity arises because such systems in the phase space have areas in which the conditions ...

The cluster expansion of the Bernoulli random field percolation probability of the cubic lattice has been built. On its basis, it has been obtained the upper guaranteed estimate of the percolation threshold and corresponding ...

It is argued that W/Z boson production in ultra-relativistic pp collisions in the fragmentation region, subject to a kinematic cut on the boson transverse momentum Q┴ > Q┴min, with 1 GeV/c << Q┴min, << MW/Z, must be dominated ...

The model that allows one to generalize the notions of the multicritical and Lifshitz points is considered. The model under consideration includes the higher powers and derivatives of order parameters. Critical phenomena ...

It is shown that regimes with chaotic behavior are also inherent in linear systems. A dynamic chaos which can arise in essentially quantum systems (not quasi-classical) is of special interest. In particular, it is shown ...
