Electroweak baryon number non-conservation and "topological condensates" in the early Universe
Steven D. Bass
Electroweak vacuum transition processes (sphalerons) in the early Universe provide a possible explanation of the baryon asymmetry. Anomaly theory suggests that these electroweak ba…
Fixed poles, polarized glue and nucleon spin structure
Steven D. Bass
We review the theory and present status of the proton spin problem with emphasis on possible gluonic and sea contributions. We discuss the possibility of a J=1 fixed pole correctio…
Probing polarized strangeness in the proton: the use of heavy quarks and the renormalization group
Steven D. Bass
Once heavy-quark corrections are take into account neutrino-proton elastic scattering provides a complementary probe of polarized strangeness in the nucleon to measurements from in…
Manifestations of anomalous glue: light-mass exotic mesons and the eta-prime nucleon coupling constant
Steven D. Bass
The light-mass exotics with J^{PC}=1^{-+} observed at BNL and CERN may have a simple explanation as dynamically generated resonances in eta-prime pi rescattering in the final state…
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.
Proton spin structure and the low-energy pp -> pp eta' reaction
Steven D. Bass
Gluonic degrees of freedom induce a contact term in the effective chiral Lagrangian description of the low-energy pp -> pp eta' reaction. The strength of this contact term is, in p…
