The Role of Vectors in Reheating
Marcos A. G. Garcia, Kunio Kaneta, Wenqi Ke +3
We explore various aspects concerning the role of vector bosons during the reheating process. Generally, reheating occurs during the period of oscillations of the inflaton condensa…
Seeking Truth and Beauty in Flavor Physics with Machine Learning
Konstantin T. Matchev, Katia Matcheva, Pierre Ramond +1
The discovery process of building new theoretical physics models involves the dual aspect of both fitting to the existing experimental data and satisfying abstract theorists' crite…
Identifying the Group-Theoretic Structure of Machine-Learned Symmetries
Roy T. Forestano, Konstantin T. Matchev, Katia Matcheva +3
Deep learning was recently successfully used in deriving symmetry transformations that preserve important physics quantities. Being completely agnostic, these techniques postpone t…
Gravitational Production of Spin-3/2 Particles During Reheating
Kunio Kaneta, Wenqi Ke, Yann Mambrini +2
We compute the density of a spin- particle, the raritron, produced at the end of inflation due to gravitational interactions. We consider a background inflaton condensate…
Cosmological Collider Signatures of Higgs- Inflation
Yohei Ema, Sarunas Verner
We study the cosmological collider signatures in the Higgs- inflation model. We consider two distinct types of signals: one originating from the inflaton coupling to Standard…
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…
A New Window into Gravitationally Produced Scalar Dark Matter
Marcos A. G. Garcia, Mathias Pierre, Sarunas Verner
Conventional scenarios of purely gravitationally produced dark matter with masses below the Hubble parameter at the end of inflation are in tension with Cosmic Microwave Background…
Isocurvature Constraints on Scalar Dark Matter Production from the Inflaton
Marcos A. G. Garcia, Mathias Pierre, Sarunas Verner
We investigate the production of a spectator scalar dark matter field that is directly coupled to the inflaton during inflation and reheating. We consider two specific inflationary…
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…
Discovering Sparse Representations of Lie Groups with Machine Learning
Roy T. Forestano, Konstantin T. Matchev, Katia Matcheva +3
Recent work has used deep learning to derive symmetry transformations, which preserve conserved quantities, and to obtain the corresponding algebras of generators. In this letter,…
Deep Learning Symmetries and Their Lie Groups, Algebras, and Subalgebras from First Principles
Roy T. Forestano, Konstantin T. Matchev, Katia Matcheva +3
We design a deep-learning algorithm for the discovery and identification of the continuous group of symmetries present in a labeled dataset. We use fully connected neural networks…
