Supernarrow Dibaryons
L. V. Fil'kov
An analysis of the experimental search for supernarrow dibaryons (SNDs) have been performed. The sum rules for SND masses have been constructed. The calculated values of the SND ma…
Dipole Polarizabilities of -Mesons
L. V. Fil'kov, V. L. Kashevarov
The main experimental works, where dipole polarizabilities of charged pions have been determined, are considered. Possible reasons for the differences between the experimental data…
Dispersion sum rules for pion polarizabilities
Lev Fil'kov, Viktor Kashevarov
An analysis of different dispersion sum rules (DSRs) for the dipole and quadrupole pion polarizabilities is carried out. We prove the absence of additional spurious singularities i…
Comment on "Polarizability of the pion: No conflict between dispersion theory and chiral perturbation theory"
L. V. Fil'kov, V. L. Kashevarov
The statement of the authors of the article Phys. Rev. C 77, 065211 (2008) that spurious singularities occur in the dispersion relation approach, where imaginary parts of the ampli…
Pion Polarizabilities
L. V. Fil'kov, V. L. Kashevarov
Recent experimental pion polarizability data are reviewed and analyzed. Data on the radiative π^+ meson photoproduction on the proton at MAMI has been used to determine the differe…
Compton Scattering on Pion and Pion Polarizabilities
L. V. Fil'kov, V. L. Kashevarov
The Compton scattering on a charged pion is studied using the dispersion relations. Unknown mass, full width and decay width into γγof the sigma meson are found from a fit to the e…
