Cosmological Constant and Axions in String Theory
Peter Svrcek
String theory axions appear to be promising candidates for explaining cosmological constant via quintessence. In this paper, we study conditions on the string compactifications und…
Axions In String Theory
Peter Svrcek, Edward Witten
In the context of string theory, axions appear to provide the most plausible solution of the strong CP problem. However, as has been known for a long time, in many string-based mod…
Bounds on masses of bulk fields in string compactifications
Shamit Kachru, John McGreevy, Peter Svrcek
In string compactification on a manifold X, in addition to the string scale and the normal scales of low-energy particle physics, there is a Kaluza-Klein scale 1/R associated with…
Gauge-Mediated Supersymmetry Breaking in String Compactifications
Duiliu-Emanuel Diaconescu, Bogdan Florea, Shamit Kachru +1
We provide string theory examples where a toy model of a SUSY GUT or the MSSM is embedded in a compactification along with a gauge sector which dynamically breaks supersymmetry. We…
Lectures on Twistor Strings and Perturbative Yang-Mills Theory
Freddy Cachazo, Peter Svrcek
Recently, Witten proposed a topological string theory in twistor space that is dual to a weakly coupled gauge theory. In this lectures we will discuss aspects of the twistor string…
Recursion Relations for Gauge Theory Amplitudes with Massive Particles
S. D. Badger, E. W. N. Glover, V. V. Khoze +1
We derive general tree-level recursion relations for amplitudes which include massive propagating particles. As an illustration, we apply these recursion relations to scattering am…
