Effect of the eta eta channel and interference phenomena in the two-pion transitions of charmonia and bottomonia
Surovtsev, Yu .S. ; Bydžovský, Petr ; Gutsche, T. ; Kaminski, R. ; Lyubovitskij, V. E. ; Nagy, M.
The basic shape of di-pion mass spectra in the two-pion transitions of both charmonia and bottomonia states is explained by a unified mechanism based on contributions of the pi pi, K (K) over bar, and eta eta coupled channels including their interference. The role of the individual f(0) resonances in shaping the di-pion mass distributions in the charmonia and bottomonia decays is considered.
