Metastable Supersymmetry Breaking in a Cooling Universe
Vadim S. Kaplunovsky
I put metastable supersymmetry breaking in a cosmological context. I argue that under reasonable assumptions, the cooling down early Universe favors metastable SUSY-breaking vacua…
Classical Renormalization of Codimension-two Brane Couplings
Claudia de Rham
The curvature on codimension-two and higher branes is not regular for arbitrary matter sources. Nevertheless, the low-energy theory for an observer on such a brane should be well-d…
Stringy Model of Cosmological Dark Energy
Irina Ya. Aref'eva
A string field theory(SFT) nonlocal model of the cosmological dark energy providing w<-1 is briefly surveyed. We summarize recent developments and open problems, as well as point o…
Quasi-exactly solvable quasinormal modes
Choon-Lin Ho, Hing-Tong Cho
We consider quasinormal modes with complex energies from the point of view of the theory of quasi-exactly solvable (QES) models. We demonstrate that it is possible to find new pote…
Bouncing and Colliding Branes
Jean-Luc Lehners
In a braneworld description of our universe, we must allow for the possibility of having dynamical branes around the time of the big bang. Some properties of such domain walls in m…
Solar System Constraints on Gauss-Bonnet Dark Energy
Stephen C. Davis
Quadratic curvature Gauss-Bonnet gravity may be the solution to the dark energy problem, but a large coupling strength is required. This can lead to conflict with laboratory and pl…
A new non-perturbative time-dependent string configuration
Jean Alexandre
A time-dependent bosonic string configuration is discussed, in graviton and dilaton backgrounds, leading to Weyl-symmetry beta-functions which are homogeneous in X^0, to any order…
Overproduction of cosmic superstrings
Neil Barnaby, Aaron Berndsen, James M. Cline +1
We show that the naive application of the Kibble mechanism seriously underestimates the initial density of cosmic superstrings that can be formed during the annihilation of D-brane…
