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…
CPT and Quantum Mechanics Tests with Kaons
Jose Bernabeu, John Ellis, Nick E. Mavromatos +2
In this review we first discuss the theoretical motivations for possible CPT violation and deviations from ordinary quantum-mechanical behavior of field-theoretic systems in the co…
