Towards Study of Light Scalar Mesons in Polarization Phenomena
N. N. Achasov, G. N. Shestakov
After a short review of the production mechanisms of the light scalars which reveal their nature and indicate their quark structure, we suggest to study the mixing of the isovector…
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)…
Reply to the "Comment on `Once more about the molecule approach to the light scalars' "
N. N. Achasov, A. V. Kiselev
The need to regularize loop integrals in a manner that preserves gauge invariance, for example, using the Pauli-Villars method, requires a subtraction that in the large mass limit…
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…
Chiral dynamics of many pion systems: the rho to 4 pi and omega to 5 pi decays
N. N. Achasov, A. A. Kozhevnikov
Based on the Weinberg lagrangian or, in a new language, the lagrangian of hidden local symmetry added with the term induced by the anomalous lagrangian of Wess and Zumino, the dyna…
