Symmetry Breaking and Reheating after Inflation in No-Scale Flipped SU(5)
John Ellis, Marcos A. G. Garcia, Natsumi Nagata +2
No-scale supergravity and the flipped SU(5)U(1) gauge group provide an ambitious prototype string-inspired scenario for physics below the string scale, which can accommodat…
A General Classification of Starobinsky-like Inflationary Avatars of SU(2,1)/SU(2) x U(1) No-Scale Supergravity
John Ellis, Dimitri V. Nanopoulos, Keith A. Olive +1
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. It has been s…
Supersymmetric Models in Light of Improved Higgs Mass Calculations
E. Bagnaschi, H. Bahl, J. Ellis +10
We discuss the parameter spaces of supersymmetry (SUSY) scenarios taking into account the improved Higgs-mass prediction provided by FeynHiggs 2.14.1. Among other improvements, thi…
De Sitter Vacua in No-Scale Supergravity
John Ellis, Balakrishnan Nagaraj, Dimitri V. Nanopoulos +1
No-scale supergravity is the appropriate general framework for low-energy effective field theories derived from string theory. The simplest no-scale Kähler potential with a single…
New Weak-Scale Physics from SO(10) with High-Scale Supersymmetry
Sebastian A. R. Ellis, Tony Gherghetta, Kunio Kaneta +1
Gauge coupling unification and the stability of the Higgs vacuum are among two of the cherished features of low-energy supersymmetric models. Putting aside questions of naturalness…
Gravitino Decay in High Scale Supersymmetry with R-parity Violation
Emilian Dudas, Tony Gherghetta, Kunio Kaneta +2
We consider the effects of R-parity violation due to the inclusion of a bilinear superpotential term in high scale supersymmetric models with an EeV scale gravitin…
