Cosmological analogies in the search for new physics in high-energy collisions

TL;DR

This paper explores analogies between early universe cosmology and high-energy particle collisions, suggesting that studying these parallels could reveal new physics through long-range correlations.

Contribution

It introduces a novel analogy framework linking cosmological evolution with hadronic collision processes to identify potential signals of new physics.

Findings

Deep connections between cosmology and particle physics are identified.

Long-range angular correlations may serve as indicators of new physics.

Analogies could guide future experimental searches for beyond Standard Model phenomena.

Abstract

In this paper, analogies between multiparticle production in high-energy collisions and the time evolution of the early universe are discussed. A common explanation is put forward under the assumption of an unconventional early state: a rapidly expanding universe before recombination (last scattering surface), followed by the CMB, later evolving up to present days, versus the formation of hidden/dark states in hadronic collisions followed by a conventional QCD parton shower yielding final-state particles. In particular, long-range angular correlations are considered pointing out deep connections between the two physical cases potentially useful for the discovery of new physics.
