Theory of Scalars
N. N. Achasov, A. V. Kiselev, G. N. Shestakov
Outline: 1. Introduction, 2. Confinement, chiral dynamics and light scalar mesons, 3. Chiral shielding of the σ(600), chiral constraints (the CGL band), the σ(600) and the f0(980)…
Lightest scalar and tensor resonances in after the Belle experiment
N. N. Achasov, G. N. Shestakov
New high statistics Belle data on the reaction cross section measured in the range of pion-pair invariant masses between 0.8 GeV and 1.5 GeV are analyzed t…
Lightest scalar in the SU_L(2)*SU_R(2) linear σmodel
N. N. Achasov, G. N. Shestakov
We consider the lightest scalar meson in the frame of the linear model, keeping in mind that this model could be the low energy realization of the two-f…
Two-Photon Production of Four-Quark States Up to the Energy
N. N. Achasov, G. N. Shestakov
Evidence for an explicitly exotic state with isospin 2 and spin-parity 2^+ near the threshold and nontrivial complementary indications of the unusual quark composition of the…
Mechanisms of the Reaction at High Energies
N. N. Achasov, G. N. Shestakov
Over the last twenty years, it was assumed that the reaction at high energies is dominated by Regge pole exchange. We show that the new Brookhav…
