Superstring-Inspired Particle Cosmology: Inflation, Neutrino Masses, Leptogenesis, Dark Matter & the SUSY Scale
John Ellis, Marcos A. G. Garcia, Natsumi Nagata +2
We develop a string-inspired model for particle cosmology, based on a flipped SU(5)U(1) gauge group formulated in a no-scale supergravity framework. The model realizes Star…
The Heavy Gluino in Natural No-Scale -(5)
Thomas Ford, Tianjun Li, James A. Maxin +1
In light of recent 80-137 results at the LHC Run 2 establishing a lower gluino mass limit of 2.25 TeV, we revisit the supersymmetric GUT model Flipped (5) with e…
From Minkowski to de Sitter in Multifield No-Scale Models
John Ellis, Balakrishnan Nagaraj, Dimitri V. Nanopoulos +2
We show the uniqueness of superpotentials leading to Minkowski vacua of single-field no-scale supergravity models, and the construction of dS/AdS solutions using pairs of these sin…
Unified No-Scale Attractors
John Ellis, Dimitri V. Nanopoulos, Keith A. Olive +1
We have presented previously a general treatment of Starobinsky-like inflation in no-scale supergravity where the tensor-to-scalar ratio , and is the tilt o…
Cosmology with a Master Coupling in Flipped SU(5) U(1): The Universe
John Ellis, Marcos A. G. Garcia, Natsumi Nagata +2
We propose a complete cosmological scenario based on a flipped SU(5) U(1) GUT model that incorporates Starobinsky-like inflation, taking the subsequent cosmological evolut…
Naturalness in D-brane Inspired Models
Ron De Benedetti, Tianjun Li, James A. Maxin +1
We examine the naturalness of the D-brane inspired model constructed in flipped supplemented with vector-like particles at the TeV scale, dubbed flippons. We find the model…
