Accelerated Discovery of Machine-Learned Symmetries: Deriving the Exceptional Lie Groups G2, F4 and E6
Roy T. Forestano, Konstantin T. Matchev, Katia Matcheva +3
Recent work has applied supervised deep learning to derive continuous symmetry transformations that preserve the data labels and to obtain the corresponding algebras of symmetry ge…
Testing the Scalar Weak Gravity Conjecture in No-scale Supergravity
Emilian Dudas, Tony Gherghetta, Keith A. Olive +1
We explore possible extensions of the Weak Gravity Conjecture (WGC) to scalar field theories. To avoid charged black hole remnants, the WGC requires the existence of a particle wit…
Supergravity Scattering Amplitudes
Emilian Dudas, Tony Gherghetta, Keith A. Olive +1
Supergravity theories with non-minimal Kähler potentials are characterized by a non-trivial field space manifold with corresponding non-trivial kinetic terms. The scattering amplit…
Slow and Safe Gravitinos
Emilian Dudas, Marcos A. G. Garcia, Yann Mambrini +3
It has been argued that supergravity models of inflation with vanishing sound speeds, , lead to an unbounded growth in the production rate of gravitinos. We consider several m…
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…
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…
