Taking into account the spin-spin interaction in two-particle weak and electromagnetic decays of pseudoscalar and vector mesons
Description
The partial widths of the decays etasub(c) → 2γ and etasub(b)→2γ are estimated taking into account the spin-spin interaction of the quark-antiquark pair inside the meson. The total etasub(c) and etasub(b)-meson widths and the mass of the etasub(b) meson are estimated. Radiative transitions J/psi → etaγ and J/psi → eta'γ are considered. The results agree with the available data
