Particle momentum spectra, correlations, and maximum entropy principle in high-multiplicity collision events

Year: 2025

Type: article

Abstract: In this paper, we utilize the maximum entropy prescription to determine a quantum state of a small collision system at the kinetic freeze-out. We derive expressions for multiplicity-selected particle momentum spectra and correlation functions by applying a fixed particle number constraint to this state. The results of our analysis can be useful for interpreting the multiplicity dependence of the particle momentum spectra and correlations in high-multiplicity p p collision events at a fixed LHC energy.
