Strings at Finite Temperature: Wilson Lines, Free Energies, and the Thermal Landscape
Keith R. Dienes, Michael Lennek, Menika Sharma
According to the standard prescriptions, zero-temperature string theories can be extended to finite temperature by compactifying their time directions on a so-called "thermal circl…
Non-perturbative Vacuum Destabilization and D-brane Dynamics
P. G. Camara, C. Condeescu, E. Dudas +1
We analyze the process of string vacuum destabilization due to instanton induced superpotential couplings which depend linearly on charged fields. These non-perturbative instabilit…
SU(5) orientifolds, Yukawa couplings, Stringy Instantons and Proton Decay
Elias Kiritsis, Michael Lennek, Bert Schellekens
We construct a large class of SU(5) orientifold vacua with tadpole cancellation both for the standard and the flipped case. We give a general analysis of superpotential couplings u…
Stringy Instanton Effects in Models with Rigid Magnetised D-branes
C. Angelantonj, C. Condeescu, E. Dudas +1
We compute instantonic effects in globally consistent T^6/Z2xZ2 orientifold models with discrete torsion and magnetised D-branes. We consider fractional branes and instantons wrapp…
Correlation Classes on the Landscape: To What Extent is String Theory Predictive?
Keith R. Dienes, Michael Lennek
In light of recent discussions of the string landscape, it is essential to understand the degree to which string theory is predictive. We argue that it is unlikely that the landsca…
Supersymmetry versus Gauge Symmetry on the Heterotic Landscape
Keith R. Dienes, Michael Lennek, David Sénéchal +1
One of the goals of the landscape program in string theory is to extract information about the space of string vacua in the form of statistical correlations between phenomenologica…
