Late Time Decay of the False Vacuum, Measurement, and Quantum Cosmology
Lawrence M. Krauss, James Dent, Glenn D. Starkman
The recent suggestion that late time quantum dynamics may be important for resolving cosmological issues associated with our observed universe requires a consideration of several s…
On the dangers of using the growth equation on large scales in the Newtonian gauge
James B. Dent, Sourish Dutta
We examine the accuracy of the growth equation , which is ubiquitous in the cosmological literature, in the context of the Newtonian gauge. By comparin…
A new perspective on the relation between dark energy perturbations and the late-time ISW effect
James B. Dent, Sourish Dutta, Thomas J. Weiler
The effect of quintessence perturbations on the ISW effect is studied for a mixed dynamical scalar field dark energy (DDE) and pressureless perfect fluid dark matter. A new and gen…
Toward a Minimum Branching Fraction for Dark Matter Annihilation into Electromagnetic Final States
James B. Dent, Robert J. Scherrer, Thomas J. Weiler
Observational limits on the high-energy neutrino background have been used to place general constraints on dark matter that annihilates only into standard model particles. Dark mat…
Electroweak Bremsstrahlung in Dark Matter Annihilation
Nicole F. Bell, James B. Dent, Thomas D. Jacques +1
A conservative upper bound on the total dark matter (DM) annihilation rate can be obtained by constraining the appearance rate of the annihilation products which are hardest to det…
Modified Pati-Salam Model from orbifolded AdS/CFT
James B. Dent, Pasquale L. Iafelice, Thomas W. Kephart
We consider models built on orbifold compactifications of the type superstring, where is the abelian group . An attractive three family $\mathca…
