The authors derive relative branching ratios for two- and three-gluon glueball decays with Fierz rearrangement and a QCD sum rule check, favoring f0(1710) and eta(2370) as glueball candidates and identifying K*(892) anti-K*(892), pi pi omega, and K Kbar phi as promising search channels.
The global factorsC 1,C 2,C 3,C 4 andC 5 appearing at different stages of the derivation are related to one another and should not be regarded as independent parameters
