Research output: Contribution to journalArticlepeer-review


The decays J/'+- and J/K+K-, &<2.0 GeV/c2, have been studied. Measurements are presented for B(f(1270))B(f(1270)'+-), B('f(1270))B(f(1270)'+-) , B(f(1525))B(f(1525)K+K-), and B('theta)B(theta(1270)K+K-). A higher-mass structure is observed in the +- channel. The spin of the theta(1720) is established with high confidence. The polarization structure of the f(1270), f(1525), and theta(1720) have been determined.
