Title: Light quark resonances in pp annihilations at 5.2 GeV/c

Abstract

Data from the Fermilab E835 experiment have been used to study the reaction pp{yields}{eta}{eta}{pi}{sup 0} at 5.2 GeV/c. A sample of 22 million six photon events has been analyzed to construct the Dalitz plot containing {approx}80k {eta}{eta}{pi}{sup 0} events. A partial wave analysis of the data has been done. Six f{sub J}-states decaying into {eta}{eta} and five a{sub J}-states decaying into {eta}{pi}{sup 0} are identified in the mass region {approx}1.3 and 2.4 GeV, and their masses, widths, and spins are determined by maximum likelihood analysis of the data. Two f{sub 0} states are identified with the popular candidates for the lightest scalar glueball, f{sub 0}(1500) and f{sub 0}(1710)
