String Scale Gauge Coupling Unification with Vector-like Exotics and Non-Canonical U(1)_Y Normalization
V. Barger, Jing Jiang, Paul Langacker +1
We use a new approach to study string scale gauge coupling unification systematically, allowing both the possibility of non-canonical U(1)_Y normalization and the existence of vect…
String Inspired Singlet Extensions of the Minimal Supersymmetric Standard Model
Tianjun Li
The only allowed Higgs superpotential term at stringy tree level in the string derived Singlet Extensions of the Minimal Supersymmetric Standard Model (SEMSSM) is h S H_d H_u, whic…
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…
Q\bar{Q} modes in the Quark-Gluon Plasma
D. Cabrera, R. Rapp
We study the evolution of heavy quarkonium states with temperature in a Quark-Gluon Plasma by evaluating an in-medium Q\bar{Q} T-matrix within a reduced Bethe-Salpeter equation in…
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…
