Di-pion emission in heavy quarkonia decays
The dipion spectrum for the ϒ(nS) → ϒ(n′S) transition with n < 4 has the form dw/dq ∼ (phase space) |η − x|2, with x = q2 − 4mπ2 / (ΔM)2 − 4mπ2 < q2 ≡ Mππ2, and ΔM = M(nS) − M(n′S). The parameter η is calculated and the spectrum is shown to reproduce the experimental data for all three types of decays: 3 → 1, 2 → 1, and 3 → 2 with η ≈ 0.5, 0, and −3, respectively.

The P matrix methods for the quark model
Abstract Physical foundations of the P-matrix approach, connecting P-matrix poles to multiquark states, are explored. The QCB interaction is constructed explicitly for ππ , π N, π K, KN and NN systems. Deuteron and tritium characteristics are calculated.

Feynman amplitudes with confinement included
Amplitudes for any multipoint Feynman diagram are written taking into account vacuum background confining field. Higher order gluon exchanges are treated within background perturbation theory. For amplitudes with hadrons in initial or final states vertices are shown to be expressed by the corresponding wave function with the renormalized z factors. Examples of two-point functions, three-point functions (form factors), and decay amplitudes are explicitly considered.

Effective range analysis of low-energy nucleon-antinucleon interaction
Abstract An effective range expansion is developed for the N N system incorporating annihilation, charge-exchange and Coulomb interaction. By fitting the LEAR data on elastic scattering and charge-exchange differential cross sections the N N scattering lengths and effective ranges are obtained. These solutions reproduce also the data on antiprotonic hydrogen, antineutron-proton total and annihilation cross sections and the behavior of the forward amplitude real-to-imaginary ratio.
