Title: Glueball Molecules

Speaker: Alexey Petrov (Wayne State University)


Glueballs are predicted in various QCD-based approaches as particles whose valence degrees of freedom are gluons. However, experimental searches for the glueballs are complicated because of the quantum-mechanical mixture of the glueball and regular qq-bar states with the same quantum numbers. I will discuss a new mechanism for hadronization of glueball states, in which glueballs form molecular bound states with regular hadrons, and its implications for the observed spectrum of hadrons. I argue that an anomalously long lifetime of the π(1800) state could result from the the fact that significant part of its wavefunction corresponds to the glueball-pion molecular state.
