In this talk, I will introduce the intriguing interplay between cosmology and strongly coupled dynamics, showing how temporary spectral features can leave lasting, observable imprints on the primordial fluctuation spectrum. Focusing on nearly conformal extensions of the Standard Model and employing AdS/CFT reasoning, I will demonstrate the emergence of gapped structures and distinct particle-like peaks in the scalar operator's spectral density within an inflationary setting. I will then estimate their contribution to cosmological observables, emphasizing unique, potentially detectable phenomena for future experiments, such as displaced oscillations in the squeezed bi-spectrum, originating from both fundamental and composite particles, and briefly touch upon the link between conformal symmetry breaking stabilization and these spectral signatures.

Collisions of high energy particles trigger multiple interactions and result in complex patterns of particles in the final state. Theoretical particle physics has been evolving continuously to deepen our understanding of these phenomena, to determine the fundamental interaction of particles and searching for unknown matters in our Universe. How might the recent advances in deep learning accelerate this process? In this talk, we will present our recent works, focusing on ideas related to Transformer architectures.
