The physics of anomalous glue
Steven D. Bass
We give a brief overview of the physics of gluonic degrees of freedom associated with the strong (QCD) axial anomaly. The role of this anomalous glue in the spin structure of the p…
The Spin Structure of the Proton and Polarized Collider Physics
S. D. Bass, A. De Roeck
We summarise the present status of the proton spin problem and the physics possibilities for future polarized ep and pp colliders. This summary is based on the presentations and di…
Proton spin structure and the axial U(1) problem
Steven D. Bass
We emphasise the relation between the spin structure of the proton and the axial U(1) problem. New experiments motivated by the proton spin problem which could shed light on the na…
Gluonic effects in eta and eta-prime physics
Steven D. Bass
We review the theory and phenomenology of the axial U(1) problem with emphasis on the role of gluonic degrees of freedom in eta and eta' production processes, especially the low-en…
Final state interaction and a light mass "exotic" resonance
Steven D. Bass, Eugenio Marco
We investigate the possibility that the light-mass exotic mesons with J^PC=1^-+ observed at BNL and CERN may be resonances in the eta-pi and eta'-pi systems associated with the ano…
Gluonic effects in eta'-nucleon interactions
Steven D. Bass
We review the theory and phenomenology of the axial U(1) problem with emphasis on the role of gluonic degrees of freedom in the low-energy pp -> pp eta and pp -> pp eta' reactions.
