Glueballs: A central mystery
F. Close
Glueball candidates and qqbar mesons have been found to be produced with different momentum and angular dependences in the central region of pp collisions. This talk illustrates th…
Determining the Gluonic Content of Isoscalar Mesons
Glennys R. Farrar
The gluonic widths of four leading glueball candidates are determined from their production in radiative quarkonium decays, allowing quantitative estimation of their glue content.…
Nucleon Spin: Summary
Frank Close
This talk summarises the discussions during the conference on the spin structure of the nucleon held at Erice; July 1995. The summary focuses on where we have come, where we are no…
Are Glueballs and Hybrids Found?
Frank Close
The lightest scalar glueball and ground state hybrids may have been found. I compare signals reported at this conference with theoretical expectations and highlight the questions t…
Hadrons and Glue at a Tau-Charm Factory
Frank Close
I discuss the special opportunities that a Tau-Charm Factory offers for identifying gluonic excitations, hybrid charmonium and other exotic hadronic states. (Invited talk at TCF Wo…
The Nucleon Spin Crisis Bible
F. E. Close
When the new data on polarised lepton nucleon scattering are compared at the same value of and with a common set of assumptions, a consistent picture of the spin content of t…
