The Glueball Filter in Central Production and Broken Scale Invariance
John Ellis, Dmitri Kharzeev
We propose a possible explanation of the kinematical dependence of the central production of the scalar glueball candidate observed recently by the WA91 and WA102 Collaborations, a…

Parity odd bubbles in hot QCD
D. Kharzeev, R. D. Pisarski, M. H. G. Tytgat
We consider the topological susceptibility for an SU(N) gauge theory in the limit of a large number of colors, . At nonzero temperature, the behavior of the topologic…

Long-Range Interactions of Small Color Dipoles
H. Fujii, D. Kharzeev
We study the scattering of small color dipoles (e.g., heavy quarkonium states) at low energies. We find that even though the couplings of color dipoles to the gluon field can be de…
