Theory Assessment and Final Theory Claim in String Theory
String Theory Final Theory Claim Underdetermination
2016/6/12
String theory has by now maintained a highly influential position in high energy physics for more than a quarter of a century. The present article analyses the reasons for the considerable trust expon...
The birth of string theory:Introduction and synopsis
early string theory dual models the analytic S-matrix Veneziano's fomula superstring theory
2016/5/30
This is a draft of the introduction to the collective volume "The birth of string theory" (CUP, 2012), including the book's index and preface. The book explores the history of the theory’s early stage...

A sufficient condition for de Sitter vacua in type IIB string theory
moduli stabilization string vacua ux compacti cations
2011/10/18
We derive a sufficient condition for realizing meta-stable de Sitter vacua with small positive cosmological constant within type IIB string theory flux compactifications with spontaneously broken supe...
The Resurgence of Instantons in String Theory
Instantons Resurgent Analysis Topological and Minimal Strings Matrix Models
2011/7/7
Nonperturbative effects in string theory are usually associated to D-branes. In many cases it can be explicitly shown that D-brane instantons control the large-order behavior of string perturbation th...

Abstract: Nonperturbative effects in string theory are usually associated to D-branes. In many cases it can be explicitly shown that D-brane instantons control the large-order behavior of string pertu...
Error Estimates in Horocycle Averages Asymptotics: Challenges from String Theory
Error Estimates Horocycle Averages Asymptotics Challenges String Theory
2011/1/21
For modular functions of rapid decay, a classical result connects the error estimate in their long horocycle average asymptotic to the Riemann hy-pothesis.
Inflation in string theory: a graceful exit to the real world
Inflation in string theory the real world
2011/1/13
The most important criteria for a successful inflation are to explain the observed temperature anisotropy in the cosmic microwave background radiation, and exiting inflation in a vacuum where it can ...
D1-brane in Constant R-R 3-form Flux and Nambu Dynamics in String Theory
D1-brane Constant R-R 3-form Flux Nambu Dynamics String Theory
2010/12/23
We consider D1-string in a constant R-R 3-form flux background and analyze its low energy limit. The leading order low energy theory has reparametrization symmetry and is a generalization of an earli...
We examine the behavior of the leading Regge trajectory of the open bosonic string in a uniform electromagnetic background and present a consistent set of Fierz-Pauli conditions for these symmetric t...
Non-perturbative String Theory from Water Waves
Non-perturbative String Theory Water Waves
2010/12/24
We use a combination of a 't Hooft limit and numerical methods to find non-perturbative solutions of exactly solvable string theories, showing that perturbative solutions in different asymptotic regim...
We construct a model of quintessence in string theory based on the idea of axion monodromy as discussed by McAllister, Silverstein and Westphal arXiv:0808.0706. In the model, the quintessence field is...
Gauge Mediated Supersymmetry Breaking and String Theory
Gauge Mediated Supersymmetry Breaking String Theory
2010/12/24
We discuss the possibility of finding scenarios within type IIB string theory compactified on Calabi-Yau orientifolds with fluxes, for realizing gauge mediated supersymmetry breaking. We find that whi...
The Cosmological Constant Problem from the Point of View of String Theory
The Cosmological Constant Problem View String Theory
2010/12/24
The quantum field theory prediction of the cosmological constant is 120 orders of magnitude higher than the observed value. This is known as the cosmological constant problem. Here, we deal with the ...
In these lecture notes, we take a closer look at the calculation of scattering amplitudes for the bosonic string. It is believed that string theories form the UV completions of (super)gravity theorie...
