Heavy quark hybrid mesons: can they exist?

Colin Morningstar, (CMU)

Abstract

Hybrid mesons in which a heavy quark and a heavy antiquark are bound by an excited gluon field are discussed. Recent lattice simulations confirm the validity of a Born-Oppenheimer treatment of such systems in the absence of light quark loops. To determine if such states can exist in nature, the crucial role of light sea quarks must be considered.
