The last decade has witnessed great experimental progress that has led to measurements of
near-threshold cross sections—polarized as well as unpolarized—of high accuracy for …

Studies of meson production at threshold in the hadron-hadron interaction began in the
fifties when sufficient energies of accelerated protons were available. A strong …

Using a resonance isobar model and an effective Lagrangian approach, from recent BES
results on J/ψ→ p¯ p η and ψ→ p¯ K+ Λ, we deduce the ratio between effective coupling …

The π N interaction is studied within a meson-exchange model and in a coupled-channels
approach which includes the channels π N, η N, as well as three effective π π N channels …

The decay widths of four-body double-pion decays d*→ pn π 0 π 0, d*→ pn π+ π−, and
isoscalar parts of d*→ pp π 0 π− and d*→ nn π+ π 0 are explicitly calculated with the help of …

We discuss consequences of the models of “tensorial pomeron” and “vectorial pomeron” for
exclusive diffractive production of scalar and pseudoscalar mesons in proton–proton …

The near-threshold ϕ-meson production in proton-proton and π-p collisions is studied with
the assumption that the production mechanism is due to the sub-N ϕ-threshold N*(1535) …

For excited nucleon states N* of arbitrary spin coupling to nucleon (N) and meson (M), we
propose a Lorentz covariant orbital-spin (L− S) scheme for the effective N* NM couplings. To …

Back in the mid-1980s, a new branch of investigation related to the interaction of eta mesons
with nuclei came into existence. It started with the theoretical prediction of possible exotic …

The production of η′ mesons in photon-and hadron-induced reactions has been revisited
in view of the recent additions of high-precision data to the world data base. Based on an …
