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…
PHOTON-2017 conference proceedings
David d'Enterria, Albert de Roeck, Michelangelo Mangano +77
This document collects the proceedings of the PHOTON 2017 conference ("International Conference on the Structure and the Interactions of the Photon", including the 22th "Internatio…
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…
Dark matter and the early Universe
A. Arbey, J. Ellis, F. Mahmoudi +1
Big-Bang nucleosynthesis (BBN) represents one of the earliest phenomena that can lead to observational constraints on the early Universe properties. It is well-known that many impo…
The Future of High-Energy Collider Physics
John Ellis
High-energy collider physics in the next decade will be dominated by the LHC, whose high-luminosity incarnation will take Higgs measurements and new particle searches to the next l…
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…
