Glueballs in 2/sup + +/ /phi//phi/ final states
In this paper we discuss the striking evidence obtained by BNL/CCNY for the g/sub T/(2010), g/sub T'/(2300) and g/sub T''/(2340) I/sup G/J/sup PC/ = 0/sup +/2/sup + +/ resonances which comprise virtually all of the ..pi../sup /minus//p ..-->.. /phi//phi/n. The complete breakdown of the expected OZI suppression, and the striking differences of these states from conventional states and background in other channels has so far only been successfully explained by assuming they are produced by 1-3 2/sup + +/ glueballs. The comparison with J//phi/ radiative decay results is made. A discussion of other glueball candidates in the light of a coupled channel analysis of the 2/sup + +/ and 0/sup + +/ channels is also made. The forthcoming search for an exotic J/sup PC/ glueball is discussed. 12 refs., 10 figs., 2 tabs.
