We study magnetically charged classical solutions of a spontaneously broken gauge theory interacting with gravity. We show that nonsingular monopole solutions exist only if the Higgs field vacuumâ€¦ (More)

The effective action for hard thermal loops in Quantum Chromodynamics (QCD) is related to a gauged Wess-Zumino-Novikov-Witten theory. Some of the technical issues of this approach are clarified andâ€¦ (More)

The generating functional for hard thermal loops in Quantum Chromodynamics is rewritten in terms of a gauged Wess-Zumino-Novikov-Witten action by introducing an auxiliary field. This shows in aâ€¦ (More)

Working in the context of spontaneously broken gauge theories, we show that the magnetically charged Reissner-NordstrÃ¶m solution develops a classical instability if the horizon is sufficiently small.â€¦ (More)

We describe the relationship between time-ordered and retarded response functions in a plasma. We obtain an expression, including the proper iÇ«-prescription, for the induced current due to hardâ€¦ (More)

The generating functional for hard thermal loops in Quantum Chromodynamics is important in setting up a resummed thermal perturbation theory, so that all terms of a given order in the couplingâ€¦ (More)

The purpose of this study is to determine the individual contribution, or importance number, of the symptoms to an analysis of depression, utilizing a neural network model. In addition, the presenceâ€¦ (More)
