Abstract
Considering the (1460) to be the physical glueball G and to mix with we then find the mixing angle to be restricted to 0.15>sin2>-0.43 from the data of 0,2 and the upper bound on (1460)2. The transition matrix element for KLG0 (bare glueball) is also computed (and found to be comparable to that for KL0). These permit the glueball contribution to KL2 and & to be significant. Finally, for large mixing angles, the decay of Ds+ into a glueball is sizable, e.g., B(Ds(1460)) can be as large as 1%, and searches for glueballs in these decays are highly desirable. © 1990 The American Physical Society.
