A note on spherically symmetric naked singularities in general dimension
Peter Langfelder, Robert B. Mann
We discuss generalizations of the recent theorem by Dafermos (hep-th/0403033) forbidding a certain class of naked singularities in the spherical collapse of a scalar field. Employi…
Geons with spin and charge
Jorma Louko, Robert B. Mann, Donald Marolf
We construct new geon-type black holes in D>3 dimensions for Einstein's theory coupled to gauge fields. A static nondegenerate vacuum black hole has a geon quotient provided the sp…
Higher Order Stability of a Radiatively Induced 220 GeV Higgs Mass
V. Elias, R. B. Mann, D. G. C. McKeon +1
The effective potential for radiatively broken electroweak symmetry in the single Higgs doublet Standard Model is explored to four sequentially subleading logarithm-summation level…
On the Tensor/Scalar Ratio in Inflation with UV Cutoff
A. Ashoorioon, R. B. Mann
Anisotropy of the cosmic microwave background radiation (CMB) originates from both tensor and scalar perturbations. To study the characteristics of each of these two kinds of pertu…
A physical basis for the phase in Feynman path integration
G. N. Ord, J. A. Gualtieri, R. B. Mann
In the path integral formulation of quantum mechanics, the phase factor Exp[iS(x[t])] is associated with every path x[t]. Summing this factor over all paths yields Feynman's propag…
Dynamical Charged N-body Equilibrium in Circular Dilaton Gravity
Ryan Kerner, Robert B. Mann
We extend the problem of circular dilaton gravity to include charged particles. We examine the two (charged) particle case in detail and find an exact equilibrium solution.…
