The Covariant Approach for the Radiative Decay of the J/Ψ Meson and Relation to Amplitudes Extracted in the Helicity Basis
A. V. Anisovich, K. V. Nikonov, A. V. Sarantsev
We have developed the covariant approach for the partial wave analysis of the radiative decay of the vector meson into two pseudoscalar mesons based on the orbital momentum- intrin…
Proton-proton, pion-proton and pion-pion diffractive collisions at ultra-high energies
V. V. Anisovich, K. V. Nikonov, V. A. Nikonov +1
The LHC energies are those at which the asymptotic regime in hadron-hadron diffractive collisions () might be switched on. Based on results of the Dakhno-Nikonov eikonal…
Proton-proton diffractive collisions at ultra-high energies
V. V. Anisovich, K. V. Nikonov, V. A. Nikonov
Proton-proton total and elastic cross sections are considered in the Dakhno-Nikonov eikonal model [L.G. Dakhno, V.A. Nikonov, Eur. Phys. J. A8, 209 (1999)] at ultra-high energies.…
Sigma-Meson and Confinement Singularity
A. V. Anisovich, V. V. Anisovich, M. A. Matveev +5
We describe the meson-meson data for the () wave at MeV in two approaches: (i) the K-matrix approach and (ii) the dispersion relation D-m…
