Reheating Metastable O'Raifeartaigh Models

Nathaniel J. Craig, Patrick J. Fox, Jay G. Wacker

In theories with multiple vacua, reheating to a temperature greater than the height of a barrier can stimulate transitions from a desirable metastable vacuum to a lower energy stat…

Supercritical stability, transitions and (pseudo)tachyons

Ofer Aharony, Eva Silverstein

Highly supercritical strings (c much greater than 15) with a time-like linear dilaton provide a large class of solutions to string theory, in which closed string tachyon condensati…

Is N = 8 Supergravity Ultraviolet Finite?

Zvi Bern, Lance J. Dixon, Radu Roiban

Conventional wisdom holds that no four-dimensional gravity field theory can be ultraviolet finite. This understanding is based mainly on power counting. Recent studies confirm that…

O'KKLT

Renata Kallosh, Andrei Linde

We propose to combine the quantum corrected O'Raifeartaigh model, which has a dS minimum near the origin of the moduli space, with the KKLT model with an AdS minimum. The combined…

Sinks in the Landscape, Boltzmann Brains, and the Cosmological Constant Problem

Andrei Linde

This paper extends the recent investigation of the string theory landscape in hep-th/0605266, where it was found that the decay rate of dS vacua to a collapsing space with a negati…

The Four-Loop Planar Amplitude and Cusp Anomalous Dimension in Maximally Supersymmetric Yang-Mills Theory

Zvi Bern, Michael Czakon, Lance J. Dixon +2

We present an expression for the leading-color (planar) four-loop four-point amplitude of N=4 supersymmetric Yang-Mills theory in 4-2 e dimensions, in terms of eight separate integ…
