MSSM via Pati-Salam from Intersecting Branes on $T^{6} / (Z_{2} \times Z_{2}^{'})$

Ching-Ming Chen, V. E. Mayes, D. V. Nanopoulos

We construct an MSSM-like model via Pati-Salam from intersecting D-branes in Type IIA theory on the $Z_{2} \times Z_{2}^{'}$ orientifold where the D-branes wrap rigid 3-cycles. Because…

Smoothly evolving Supercritical-String Dark Energy relaxes Supersymmetric-Dark-Matter Constraints

A. B. Lahanas, N. E. Mavromatos, D. V. Nanopoulos

We show that Supercritical-String-Cosmology (SSC) off-equilibrium and time-dependent-dilaton effects lead to a smoothly evolving dark energy for the last 10 billion years in concor…

Testable Flipped SU(5) x U(1)_X Models

Jing Jiang, Tianjun Li, Dimitri V. Nanopoulos

The little hierarchy between the GUT scale and the string scale may give us some hints that can be tested at the LHC. To achieve string-scale gauge coupling unification, we introdu…

Dilaton and off-shell (non-critical string) effects in Boltzmann equation for species abundances

A. B. Lahanas, N. E. Mavromatos, D. V. Nanopoulos

In this work we derive the modifications to the Boltzmann equation governing the cosmic evolution of relic abundances induced by dilaton dissipative-source and non-critical-string…

Dissipative Liouville Cosmology: A Case Study

G. A. Diamandis, B. C. Georgalas, A. B. Lahanas +2

We consider solutions of the cosmological equations pertaining to a dissipative, dilaton-driven off-equilibrium Liouville Cosmological model, which may describe the effective field…

Flipped and Unflipped SU(5) as Type IIA Flux Vacua

Ching-Ming Chen, Tianjun Li, Dimitri V. Nanopoulos

On Type IIA orientifolds with flux compactifications in supersymmetric AdS vacua, we for the first time construct SU(5) models with three anti-symmetric {\bf 10} representations an…
