A model of glueballs by Buniy, Roman V., Kephart, Thomas W.

“…We model the observed glueball mass spectrum in terms of energies for tightly knotted and linked QCD flux tubes. The data is fit well with one parameter. We…”

Semiclassical gravity and invisible axions by HOLMAN, R, KEPHART, T. W, SOO-JONG REY

“…We show that charged Eguchi-Hanson instantons represent a [ital calculable], intrinsic quantum gravity breaking of the Peccei-Quinn symmetry. The size of such…”

Inflation and generalized O'Raifeartaigh SUSY models by Berera, Arjun, Kephart, Thomas W

“…Thermal inflation usually requires an inflationary potential with nonrenormalizable operators (NROs). We demonstrate how O'Raifeartaigh models with or without…”

Space–time foam and cosmic-ray interactions by Jankiewicz, Marcin, Buniy, Roman V., Kephart, Thomas W., Weiler, Thomas J.

“…It has been proposed that propagation of cosmic-rays at extreme-energy may be sensitive to Lorentz-violating metric fluctuations (“foam”). We investigate the…”

Signatures for a cosmic flux of magnetic monopoles by Wick, Stuart D., Kephart, Thomas W., Weiler, Thomas J., Biermann, Peter L.

“…Any early Universe phase transition occurring after inflation has the potential to populate the Universe with relic magnetic monopoles. Observations of…”

Wormhole cosmology and the horizon problem by HOCHBERG, D, KEPHART, T. W

“…We construct an explicit class of dynamic Lorentzian wormholes connecting Friedman-Robertson-Walker spacetimes. These wormholes can allow two-way transmission…”

Analytical Debye-Huckel model for electrostatic potentials around dissolved DNA by Wagner, K., Keyes, E., Kephart, T.W., Edwards, G.

“…We present an analytical, Green-function-based model for the electric potential of DNA in solution, treating the surrounding solvent with the Debye-Huckel…”

The constraints on N=1 supergravities and type I superstrings from 2-loop chiral anomalies by Cutler, III, R.W., Kephart, T.W.

“…N=1 supergravities with SO(2 2 n+1 ) gauge groups are local chiral anomaly free at 1-loop in D=4 n+2 dimensions ( n≥0), as are SO(32) type I superstrings in 10…”

Gauge field back reaction on a black hole by HOCHBERG, D, KEPHART, T. W

“…The order-[h bar] fluctuations of gauge fields in the vicinity of a black hole can create a repulsive antigravity region extending out beyond the renormalized…”

Binary icosahedral flavor symmetry for four generations of quarks and leptons by Chen, Chian-Shu, Kephart, Thomas W., Yuan, Tzu-Chiang

“…To include the quark sector, the (icosahedron) four generation lepton model is extended to a binary icosahedral symmetry I′ flavor model. We find that the…”

Chromoelectric dipole moments of heavy quarks and purely gluonic CP violating operators by DARWIN CHANG, KEPHART, T. W, WEI-YEE KEUNG, TZU CHIANG YUAN

“…We study effects of induced {ital CP}-nonconserving effective operators involving the gluon field strength as a result of integrating out the heavy-quark field…”

Luminous axion clusters by KEPHART, T. W, WEILER, T. J

“…It is suggested that the density fluctuations of axionic dark matter may have measureable luminosities. Depending on the axionic mass, it is shown that the…”

Cosmological dispersion, the corrected redshift formula, and large-scale structure by HOCHBERG, D, KEPHART, T. W

“…We calculate the exact frequency redshift for both massless and massive scalar fields coupled to gravity in Friedmann-Robertson-Walker backgrounds. The exact…”

Phenomenology of the aspon model of CP violation by FRAMPTON, P. H, NG, D, KEPHART, T. W, WEILER, T. J

“…The aspon model of spontaneous {ital CP} violation solves the strong {ital CP} problem and gives a new mechanism for weak {ital CP} violation. It predicts a…”
