Experimental Status of QCD Glueballs

A review of the experimental status of QCD Glueballs, and the history of major investigations and developments in the research are presented. The most important missing link in experimentally establishing QCD is the lack of consensus on the experimental establishment of at least one glueball. Therefore the lecture focused on what, if any, experimental evidence can be considered compelling for the establishment of at least one Glueball. The unique experimental evidence for the I^GJ^PC = 0⁺2⁺⁺ Glue-ball, has only been successfully explained in over two decades by interaction with the 2⁺⁺ Glueball. Therefore it is resonable to conclude that the 2⁺⁺ Glueball has been experimentally established.
