title: Search for parity-nonconservation effects in deep-inelastic μ-N interaction
abstract: The difference of the cross sections for deep inelastic scattering of muons with average momenta 21 GeV/ c with right and left helicity at large angles, i.e., with large momentum transfer, has been measured. No statistically-significant dependence of cross sections on the longitudinal polarization of muons has been found, i.e. no parity-nonconservation effects in deep inelastic μN interaction have been observed. The magnitude of the cross-section asymmetry R = [〈σ R 〉 − 〈σ L 〉] [〈σ R 〉+ + 〈σ L 〉] may be represented as R = β 〈 Q 2 〉 = (− 4 ± 6) × 10 −3 〈 Q 2 , (GeV/ c ) 2 〉. The limitations G o ( μ ) = (+ 6 ± 10) G have been obtained for the constant G o ( μ ) of vector-axial interaction ( G o (μ) 2 ) [ μ γα(1 + γ 5 )μ] J α o (hadron, V-A).

title: The unitarity condition for the resonance-particle amplitude
abstract: The unitarity conditions (UC) for the resonance-particle amplitude are explicitly deduced from the exact three-body UC. In case where two pairs out of three particles resonate an additional term changes the quasi two-body form of the UC. Its presence is shown to guarantee the real analyticity of the resonance-particle amplitude. The UC obtained possess two classes of solutions, singular or regular at the Peierls points. Comparison with the Fredholm denominator of the Faddeev equation for the resonance-particle amplitude enables one to choose the unique solution having no Peierls singularities. The linear integral equation for the denominator of the resonance-particle amplitude is explicitly written and discussed.

title: Resolution of the pion puzzle: The QCD string in Nambu-Goldstone mesons
abstract: Pions and kaons have a double nature: the chiral dynamics of Nambu-Goldstone bosons together with the usual string dynamics common to all mesons. To uncover the interplay of both dynamics, the effective chiral Lagrangian is derived from the QCD Lagrangian using the field correlator method, and the pion self-energy (mass) operator is written explicitly. The latter contains an infinite number of poles, but is normalized to zero at zero momentum because of spontaneous chiral symmetry breaking. As a result, one obtains the Gell-Mann-Oakes-Renner relation for the ground-state pion and (slightly shifted by chiral dynamics) the usual spectrum of radially excited pions starting with π(1300).

title: Nonperturbative dynamics in the chromomagnetic QCD vacuum above the deconfinement temperature
abstract: We investigate the residual chromomagnetic nonperturbative interaction between colour sources which survives above the deconfinement temperature. This interaction is demonstrated to be attractive enough to support bound states of quarks (and gluons). Although, for heavy quarks, such bound states appear to be very shallow and thus to dissociate easily, for light quarks (and gluons), the interaction is found to be strong enough to lead to quark (gluon) pair creation in the vacuum and thus to a complete rebuild of the vacuum state.

title: Heavy quark bound states above deconfinement
abstract: A comprehensive study of the color singlet heavy quark states above T_c is given, using the Field Correlator Method (FCM) for nonperturbative Q{\bar Q} potentials and the screened Coulomb potential with the T-dependent Debye radius. Using these potentials we calculate binding energies and melting temperatures of heavy mesons and baryons in the deconfined phase of quark-gluon plasma and the J/\psi and Upsilon disintegration cross sections via the gluon absorption.
