Glueball-qq filter in central hadron production
Abstract
Glueballs and qq of the same JPC are distinguishable due to their boson versus fermion internal structure. This leads to a different topology for central production of glueballs and qq. We apply this test to data from the WA102 experiment and find that the f0(1500) and the f2(1900) show behaviour consistent with glueballs and opposite to that expected if they were pure qq states.
