An Invariant Characterization of the Levi-Civita Spacetimes
C. K. Watson, W. Julius, M. Gorban +3
In the years 1917-1919 Tullio Levi-Civita published a number of papers presenting new solutions to Einstein's equations. This work, while partially translated, remains largely inac…
Investigation of Quasi--Realistic Heterotic String Models with Reduced Higgs Spectrum
G. Cleaver, A. E. Faraggi, J. Greenwald +4
Quasi--realistic heterotic-string models in the free fermionic formulation typically contain an anomalous U(1), which gives rise to a Fayet-Iliopolous term that breaks supersymmetr…
Free Fermionic Heterotic Model Building and Root Systems
M. Robinson, G. Cleaver, M. Hunziker
We consider an alternative derivation of the GSO Projection in the free fermionic construction of the weakly coupled heterotic string in terms of root systems, as well as the inter…
Minimal Superstring Standard Model: A Review
G. B. Cleaver
I review a heterotic-string solution in which the observable sector effective field theory just below the string scale reduces to that of the MSSM, with the standard observable gau…
Flat Directions in Flipped SU(5) I: All-Order Analysis
G. B. Cleaver, J. Ellis, D. V. Nanopoulos
We present a systematic classification of field directions for the string-derived flipped SU(5) model that are D- and F-flat to all orders. Properties of the flipped SU(5) model wi…
Towards String Predictions
G. B. Cleaver, A. E. Faraggi, D. V. Nanopoulos +1
The aim of superstring phenomenology is to develop the tools and methodology needed to confront string theory with experimental data. The first mandatory task is to find string sol…
