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…

Note on a NAHE Variation
Jared Greenwald, Douglas Moore, Kristen Pechan +3
We present a variation of the NAHE-basis for free fermionic heterotic string models. By rotating some of the boundary conditions of the NAHE periodic/anti-periodic fermions {y^m, \…

Classification of the FRW universe with a cosmological constant and a perfect fluid of the equation of state
Te Ha, Yongqing Huang, Qianyu Ma +5
We systematically study the evolution of the Friedmann-Robertson-Walker (FRW) universe coupled with a cosmological constant and a perfect fluid that has the equation of state $…
