QCD Vacuum Topology and Glueballs
Hilmar Forkel
We outline a comprehensive study of spin-0 glueball properties which, in particular, keeps track of the topological gluon structure. Specifically, we implement (semi-hard) topologi…

Yang-Mills instantons in closed Robertson-Walker spacetime
Hilmar Forkel
We construct a four-parameter class of self-dual instanton solutions of the classical SU(2)-Yang-Mills equations in a closed Euclidean Robertson-Walker space-time.

Topological charge screening and pseudoscalar glueballs
Hilmar Forkel
Topological charge screening in the QCD vacuum is found to provide crucial nonperturbative contributions to the short-distance expansion of the pseudoscalar (0^{-+}) glueball corre…
