Relative phase between the three-gluon and one-photon amplitudes of the J/psi decays
N. N. Achasov
Abstract
It is shown that the study of the ω-ρinterference pattern in the J/psi -> (rho+omega)eta -> pi+pi-eta decay provides evidence for the large (nearly 90 degrees) relative phase between the isovector one-photon and three-gluon decay amplitudes.
