Resonances in a sudden chemical freeze-out model

TL;DR

This paper compares equilibrium and non-equilibrium models' predictions for resonance particle spectra in Pb+Pb collisions at LHC energies, aiming to distinguish between the models based on resonance behavior.

Contribution

It provides predictions for resonance spectra in different models, highlighting potential experimental signatures to differentiate equilibrium from non-equilibrium scenarios.

Findings

Differences in resonance spectra could distinguish models.

Predictions include multiple resonances such as eta, rho, Sigma(1385), Lambda(1520), and Xi(1530).

Model distinctions may be observable in experimental data.

Abstract

The prediction for $p_T$ spectra of various resonances produced in Pb+Pb collisions at 2.76 TeV at the LHC in equilibrium and non-equilibrium models is made. It includes the $\eta$, $\rho$(770), $\Sigma$(1385), $\Lambda$(1520), and $\Xi$(1530). The apparent differences may allow to distinguish between the models.
