Description
The paper describes a study of angular correlations in the phiphi system produced in the reaction π-Be->phiphi+X at 85 GeV/c. A sample of 33851 candidate phiphi events with phiphi mass less than 3.2 GeV/c2 was obtained in an experiment using the OMEGA spectrometer at CERN with a 4-kaon trigger. Moments of the decay angular distributions are presented as a function of phiphi mass over the range 2.0 to 3.2 GeV/c2. The distributions in the mass interval 2.0-2.5 GeV/c2 are best fitted by a dominance of Jsup(P)=2+. A signal in the H(222200) moment in the mass interval 2.9-3.0 GeV/c2 is interpreted as due to etasub(c)->phiphi and yields a value for (cross section) x (branching ratio) = 14.1+-6.3 nb/nucleon.
