Model-Independent Confirmation of the $σ$ -Meson below 1 GeV and Indication for the $f_{0} (1500)$ Glueball

Yu. S. Surovtsev, D. Krupa, M. Nagy

In the model-independent approach consisting in the immediate application to the analysis of experimental data of such general principles as analyticity and unitarity, a confirmati…

Confirmation of the $σ$ -Meson below 1 GeV and Indication for the $f_{0} (1500)$ Glueball

Yu. S. Surovtsev, D. Krupa, M. Nagy

On the basis of a simultaneous description of the isoscalar s-wave channel of the $π π$ scattering (from the threshold up to 1.9 GeV) and of the $π π \to K K ˉ$ process (from the t…

Nucleon structure from the quasithreshold inverse pion electroproduction

T. D. Blokhintseva, M. Nagy, Yu. S. Surovtsev

The process $π N \to e^{+} e^{-} N$ (IPE), being a natural and unique laboratory for studying the hadron electromagnetic structure in the sub- $N N ˉ$ -threshold time-like region of the…

The relativistic particle with curvature and torsion of world trajectory

S. A. Gogilidze, Yu. S. Surovtsev

Local symmetries of the action for a relativistic particle with curvature and torsion of its world curve in the (2+1)-dimensional space-time are studied. With the help of the metho…

Quasigroup of Local-Symmetry Transformations in Constrained Theories

N. P. Chitaia, S. A. Gogilidze, Yu. S. Surovtsev

In the framework of the generalized Hamiltonian formalism by Dirac, the local symmetries of dynamical systems with first- and second-class constraints are investigated in the gener…
