Chiral dynamics of many pion systems: the rho to 4 pi and omega to 5 pi decays
N. N. Achasov, A. A. Kozhevnikov
Based on the Weinberg lagrangian or, in a new language, the lagrangian of hidden local symmetry added with the term induced by the anomalous lagrangian of Wess and Zumino, the dyna…

Exclusive hadron production in e^+e^- collisions up to the J/psi energy
N. N. Achasov, A. A. Kozhevnikov
The predictions are presented for the diagonal and transition form factors of light hadrons in the time-like region up to the production threshold of an open charm quantum number.…

Decay of Z-string due to the fermion emission
A. A. Kozhevnikov
The question of classical topological stability of the gauge vortex defects is reanalyzed upon taking into account the quantum perturbative effects. The purely Abelian Higgs string…
