Observation of structure in the phi phi system produced in radiative J/psi decays
A sample of 4.9 million JI'I/J decays from the Mark III detector at SPEAR is used to study the radiative decay J I'I/J ---+ i¢¢. The decay is observed in two final states; iK+K-K+K-and the previously unobserved iK+K-K sKl. The new final state and an improved analysis of the all charged state allow …
