Alternative Form of the Parity-Violating Current for the Hyperon Weak Radiative Decays and Hara Theorem
E. N. Bukina, V. M. Dubovik, V. S. Zamiralov
It is shown that upon considering an alternative form of a parity-violating part of the transition electromagnetic current it is possible to reformulate Hara theorem in a way that…
The gauge freedoms of enlarged Helmholtz theorem and the Neumann --- Debye potentials; their manifestation in the multipole expansion of conserved current
E. N. Bukina, V. M. Dubovik
We discuss gauge freedom within the scope of the enlarged Helmholtz theorem and Neumann-Debye decomposition and then demonstrate its realization for the multipole expansion of a el…
Upon symmetry of baryon magnetic moments in the chiral and the quark-soliton models
E. N. Bukina, V. M. Dubovik, V. S. Zamiralov
It is shown that the baryon magnetic moment descriptions in the frameworks of the chiral model ChPT and the quark soliton one are practically identical. The main difference…
Evaluation of Vacuum Energy for Tensor Fields on Spherical Spaces
E. N. Bukina, N. N. Shtykov
The effective one-loop potential on spaces for massless tensor fields is evaluated. The Casimir energy is given as a value of function by means of which re…
