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…
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…
