Near-Maximal Mixing of Scalar Gluonium and Quark Mesons: A Gaussian Sum-Rule Analysis

D. Harnett, R. T. Kleiv, K. Moats +1

Gaussian QCD sum-rules are ideally suited to the study of mixed states of gluonium (glueballs) and quark ($q\bar{q}$) mesons because of their capability to resolve widely-separated…
