1. Naturalness in D-brane inspired models / Benedetti, Ron ; Li, Tianjun ; Maxin, James ; Nanopoulos, Dimitri
We examine the naturalness of the D-brane inspired model constructed in flipped SU(5) supplemented with vector-like particles at the TeV scale, dubbed flippons. [...]

2. A general classification of Starobinsky-like inflationary avatars of SU(2,1)/SU(2)×U(1) no-scale supergravity / Ellis, John ; Nanopoulos, Dimitri ; Olive, Keith ; Verner, Sarunas
Measurements of the cosmic microwave background (CMB) favour models of inflation with a small tensor-to-scalar ratio r , as predicted by the Starobinsky R + R 2 model. [...]

3. Inspiration from intersecting D-branes: general supersymmetry breaking soft terms in no-scale F - SU (5) / De Benedetti, Ron ; Li, Chuang ; Li, Tianjun ; Lux, Adam ; et al
Motivated by D-brane model building, we evaluate the F - SU (5) model with additional vector-like particle multiplets, referred to as flippons, within the framework of No-Scale Supergravity with non-vanishing general supersymmetry breaking soft terms at the string scale. [...]

5. From R2 gravity to no-scale supergravity / Ellis, John ; Nanopoulos, Dimitri V. ; Olive, Keith A.
We show that R2 gravity coupled conformally to scalar fields is equivalent to the real bosonic sector of SU(N,1)/SU(N)×U(1) no-scale supergravity, where the conformal factor can be identified with the Kähler potential, and we review the construction of Starobinsky-like models of inflation within this framework..

6. Probing the No-Scale F - SU (5) one-parameter model via gluino searches at the LHC2 / Li, Tianjun ; Maxin, James A. ; Nanopoulos, Dimitri V.
In our recent paper entitled “The return of the King: No-Scale F - SU(5) ”, we showed that the model space supporting the most favorable phenomenology should have been probed in 2016 at the LHC2, with an even further reach into this region of the model in 2017–18. [...]

8. No-scale SU(5) super-GUTs / Ellis, John ; Evans, Jason L. ; Nagata, Natsumi ; Nanopoulos, Dimitri V. ; et al
We reconsider the minimal SU(5) grand unified theory (GUT) in the context of no-scale supergravity inspired by string compactification scenarios, assuming that the soft supersymmetry-breaking parameters satisfy universality conditions at some input scale Min above the GUT scale MGUT . [...]

9. The return of the King: No-Scale F - SU (5) / Li, Tianjun ; Maxin, James A. ; Nanopoulos, Dimitri V.
We revisit the viable parameter space in No-Scale F - SU(5) , examining the Grand Unified Theory within the context of the prevailing gluino mass limits established by the LHC. [...]

10. Starobinsky-like inflation and neutrino masses in a no-scale SO(10) model / Ellis, John ; Garcia, Marcos A.G. ; Nagata, Natsumi ; Nanopoulos, Dimitri V. ; et al
Using a no-scale supergravity framework, we construct an SO(10) model that makes predictions for cosmic microwave background observables similar to those of the Starobinsky model of inflation, and incorporates a double-seesaw model for neutrino masses consistent with oscillation experiments and late-time cosmology [...]
