Glueball-meson molecules
نویسندگان
چکیده
Experimental searches for pure glueball states have proven challenging and so far yielded no results. This is believed to occur because glueballs mix with the ordinary qq¯ same quantum numbers. We will discuss an alternative mechanism, formation of glueball-meson molecular states. argue that wave functions already observed excited meson may contain a significant part due such phenomenology molecules comment on possible charmless component XYZ

New Glueball-Meson Mass Relations
Using the “glueball dominance” picture of the mixing between qq̄ mesons of different hidden flavors, we establish new glueball-meson mass relations which serve as a basis for glueball spectral systematics. For the tensor glueball mass 2.3 ± 0.1 GeV used as an input parameter, these relations predict the following glueball masses: M(0) ≃ 1.65 ± 0.05 GeV, M(1) ≃ 3.2 ± 0.2 GeV, M(2) ≃ 2.95 ± 0.15 G...
متن کاملof meson , hybrid , and glueball states
The effective QCD Hamiltonian is constructed with the help of the background perturbation theory, and relativistic Feynman–Schwinger path integrals for Green's functions. The resulting spectrum displays mass gaps of the order of one GeV, when additional valence gluon is added to the bound state. Mixing between meson, hybrid, and glueball states is defined in two ways: through generalized Green'...
متن کاملScalar meson and glueball decays within a effective chiral approach
We study the strong and electromagnetic decay properties of scalar mesons above 1 GeV within a chiral approach. The scalar-isoscalar states are treated as mixed states of quarkonia and glueball configurations. A fit to the experimental decay rates listed by the Particle Data group is performed to extract phenomenological constraints on the nature of the scalar resonances. A comparison to other ...
متن کاملHadronic molecules : meson - baryon hybrids
The existence of hadronic molecular-type hybrids consisting of a baryon and a meson is argued. Long-range interactions due to one-pion exchange are shown to be strong enough to produce a loosely bound state. Specific features of a molecular hybrid are discussed.
متن کاملExotic meson-meson molecules and compact four–quark states
We present an exact calculation of S and P wave QQn̄n̄ states using different standard nonrelativistic quark–quark potentials. We explore in detail the charm and bottom sectors looking for bound states that could be measured within existing facilities. Against the proliferation of four–quark states sometimes predicted in the literature, we found a small number of candidates to be stable. We analy...
