“…Transverse momentum (p T ) is supposed to be greater in the Pb-forward going direction as compared to the protons-forward direction because of asymmetric distribution of incident center of mass energy in p+Pb colliding system [14,15]. The measurements of strange-particles' p T spectra in p+Pb, and Pb+Pb collisions as a function of event multiplicity are already reported [16,17]. Here in this article we specifically look at the spectra of p p + + -, + + -K K and + p p ¯particles p T spectra in collisions involving p+Pb, and Xe+Xe at 5.02 TeV and 5.44 TeV, respectively, in the rapidity range 0 < y CM < 0.5.…”

This paper is focused on comparative analysis of transverse momentum ( ) distributions across two different sets of experimental data from ALICE at the LHC, juxtaposing with the Monte-Carlo models EPOS-LHC and EPOS 1.99 simulations. The chosen collision sets have approximately same per nucleon energy. We analyze the transverse momentum spectra of hadrons ( , and ) in p+Pb collisions at 5.02 TeV, and Xe+Xe collisions at 5.44 TeV spanning a rapidity range of 0 < yCM < 0.5, centrality of 0 to 5 % (the most central or head-on collisions). Analysis of the Hadrons yield is crucial for understanding the mechanism of underlying hadronization in the hot and dense quark matter produced in relativistic heavy ion collisions. The experimental results are compared with the predictions of hydrodynamic models EPOS-LHC and EPOS-1.99. It is notably found that the maximum yields of various particles occur at low . Furthermore, the comparison showed a slightly better agreement between experimental results and the predictions of the EPOS-LHC as opposed to that of EPOS-1.99. The EPOS-LHC model significantly shows an enhanced agreement with experimental results in the case of Xe+Xe collisions as compared to p+Pb collisions.

“…Proton-proton (pp) collisions provide baseline measurements for heavy ion interactions and insights into the particle production mechanisms and serve as a valuable tool for tuning the parameters of hadronic Monte Carlo generators [10,11]. Since the initial states of colliding systems in high-energy colliders do not have strange content, information on the final strangeness production is crucial to study the properties of the strongly interacting medium created in high-energy collisions [12]. At high transverse momentum (p T ), the production of strange hadrons is dominated by flavor creation and excitation at the early evolution of high-energy collisions.…”

Tuning Monte Carlo Models to Reproduce Cosmic Radiation Interacting with the Earth’s Atmosphere

In this work, we performed a comparative study between HIJING, Sibyll, and QGSJET model-based event generators. Such Monte Carlo (MC) models are used to simulate the interaction and propagation of high-energy cosmic radiation (e.g., coming from the sun) with the Earth’s atmosphere. The global event observables selected for the study were the transverse momentum (pT) spectra and rapidity density distributions of strange particles (KS0, Λ, and Ξ−). This study was performed in the STAR and CMS fiducial phase spaces by simulating the strange particles in pp collisions at s = 200 GeV, 900 GeV, and 7 TeV, and the simulations were then compared to the experimental measurements. It was observed that none of the discussed model-based event generators ultimately predicted the experimental results, except QGSJET, which generally agrees reasonably with the data. However, QGSJET does not produce Ξ particles; therefore, it does not provide any predictions for Ξ. The other two models reproduced the data only in a limited rapidity or transverse momentum region while mainly underpredicting the data in the rest of the areas. These cosmic radiation simulation models are capable of covering the mid-rapidity regions of density distributions. Utilizing model-based observations, some fundamental parameters can be re-tuned and extrapolations to the highest energies can be investigated. Furthermore, these observations can provide valuable insights that could potentially constrain and improve perturbative- and non-perturbative-based QCD event generators, thereby facilitating a better understanding of the underlying physics.
