Phenomenological description of the $D_{s 0}^{*} (2317) \to D_{s} π^{0}$ decay

N. N. Achasov, G. N. Shestakov

For coupled channels $D^{0} K^{+}$ , $D^{+} K^{0}$ , $D_{s}^{+} η$ , and $D_{s}^{+} π^{0}$ , the $S$ -wave scattering amplitudes are constructed taking into account the mixing of the isoscalar resonance $D^*…

Toward an estimate of the amplitude $X (3872) \to π^{0} χ_{c 1} (1 P)$

N. N. Achasov, G. N. Shestakov

The well-known model of the triangle diagrams with $D^{*} D ˉ D^{*}$ and $D ˉ^{*} D D ˉ^{*}$ mesons in the loops is compared with the modern data on the amplitude of the $X(3872)\toπ^…

Generalized Vector Dominance Model up to 2 GeV

N. N. Achasov, A. V. Kiselev, A. A. Kozhevnikov

The processes $e^{+} e^{-} \to π^{+} π^{-}, ω π^{0}, η π^{+} π^{-}, K^{+} K^{-}, π^{+} π^{-} π^{0}$ are described simultaneously in the frame of the Generalized Vector Dominance Model (GVDM) allowing model error.…

Fate of Light Scalar Mesons

N. N. Achasov

It is shown that all predictions for the light scalars, based on their four-quark nature, are supported by experiment. The future research program is outlined also.

Electro-weak production of pseudovector C-even heavy quarkonia in electron-positron collisions on Belle II and BES III

Nikolay Achasov

It is shown that the molecular model for the X{3872) state contradicts the new experimental data as well as the old ones. It is suggested to study the χ_{c1} and χ_{b1} states in t…
