1. A minimal SU(5) SuperGUT in pure gravity mediation / Evans, Jason L. ; Nagata, Natsumi ; Olive, Keith A.
The lack of evidence for low-scale supersymmetry suggests that the scale of supersymmetry breaking may be higher than originally anticipated. [...]

2. Radiative production of nonthermal dark matter / Kaneta, Kunio ; Mambrini, Yann ; Olive, Keith A.
We compare dark matter production from the thermal bath in the early universe with its direct production through the decay of the inflaton. [...]

3. New weak-scale physics from SO(10) with high-scale supersymmetry / Ellis, Sebastian A. R. ; Gherghetta, Tony ; Kaneta, Kunio ; Olive, Keith A.
Gauge coupling unification and the stability of the Higgs vacuum are among two of the cherished features of low-energy supersymmetric models. [...]

4. Gravitino decay in high scale supersymmetry with R-parity violation / Dudas, Emilian ; Gherghetta, Tony ; Kaneta, Kunio ; Mambrini, Yann ; et al
We consider the effects of R-parity violation due to the inclusion of a bilinear μLHu superpotential term in high-scale supersymmetric models with an EeV scale gravitino as dark matter. [...]

5. Uncertainties in WIMP dark matter scattering revisited / Ellis, John ; Nagata, Natsumi ; Olive, Keith A.
We revisit the uncertainties in the calculation of spin-independent scattering matrix elements for the scattering of WIMP dark matter particles on nuclear matter. [...]

6. Stop coannihilation in the CMSSM and SubGUT models / Ellis, John ; Evans, Jason L. ; Luo, Feng ; Olive, Keith A. ; et al
Stop coannihilation may bring the relic density of heavy supersymmetric dark matter particles into the range allowed by cosmology. [...]

7. The Constrained NMSSM with right-handed neutrinos / Cerdeño, David G. ; De Romeri, Valentina ; Martín-Lozano, Víctor ; Olive, Keith A. ; et al
In this article, we demonstrate that the inclusion of right-handed neutrino superfields in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) makes it possible to impose universality conditions on the soft supersymmetry-breaking parameters at the Grand Unification scale, alleviating many of the problems of the so-called Constrained NMSSM. [...]

8. 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..

9. 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 . [...]

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 [...]
