“…To achieve the same, centrality bins Yet another way to examine and predict the MDs, is to plot MDs in terms of KNO scaling variable Z (= N ch / N ch ). It has been observed that MDs in hadron-hadron collisions exhibit a universal behavior in a wide range of incident energies if plotted as N ch P (N ch ) against the variable Z [20,21,22,23,24,25]. It was shown that MDs corresponding to pp collisions in the energy range ∼ (50 -303) GeV are nicely reproduced by the functional form given by Slattery [22].…”

Multiplicity distributions and event-by-event multiplicity fluctuations in AuAu collisions at energies in future heavy-ion experiment at the Facility for Anti-proton and Ion Research (FAIR) are investigated. Events corresponding to FAIR energies are simulated in the frame work of Ultra Relativistic Quantum Molecular Dynamics (URQMD) model. It is observed that the mean and the width of multiplicity distributions monotonically increase with beam energy. The trend of variations of dispersion with mean number of participating nucleons for the centrality-bin width of 5% are in accord with the Central Limit Theorem. The multiplicity distributions in various centrality bins as well as for full event samples are observed to obey Koba, Nielsen and Olesen (KNO) scaling. The trends of variations of scaled variance with beam energy are also found to support the KNO scaling predictions for larger collision centrality. The findings also reveal that the statistical fluctuations in 5% centrality-bin width appear to be under control.

“…32 test the validity of the scaling hypothesis in the case of proton-nucleus interactions. Martin et al [98] found that for nuclear emulsion the parameters in the Slattery scaling function have to be modified in order to get a reasonable fit to the experimental data in the energy range 30 -200 GeV/c. Hébert et al [99] pointed out that since emulsion is a composite target, it is not valid to reduce the multiplicity distribution to the form applicable to p+p collisions.…”

The Main Injector Particle Production (MIPP) experiment is a fixed target hadron production experiment at Fermilab. MIPP is a high acceptance spectrometer which provides excellent charged particle identification using Time Projection Chamber (TPC), Time of Flight (ToF), multicell Cherenkov (Ckov), ring imaging Cherenkov (RICH) detectors, and Calorimeter for neutrons. The MIPP experiment is designed to measure particle production in interactions of 120 GeV/c primary protons from the Main Injector and secondary beams of π ± , K ± , p andp from 5 to 90 GeV/c on nuclear targets which include H, Be, C, Bi and U, and a dedicated run with the NuMI target. The goal of the experiment is to measure hadron production cross sections or yields using these beams and targets. These hadronic interaction data can have a direct impact on the detailed understanding of the neutrino fluxes of several accelerator-based neutrino experiments like MINOS, MINERνA, NOνA and ELBNF. In this thesis, we present inelastic cross section measurements for 58 and 85 GeV/c p+p interactions, and 58 and 120 GeV/c p+Be, p+C and p+Bi interactions. A new method is described to account for the low multiplicity inefficiencies in the interaction trigger using KNO scaling. Inelastic cross sections as a function of multiplicity are also presented for p+H and p+C interactions at different beam momenta. The MIPP data are compared with the Monte Carlo predictions and existing data. We also describe an algorithm to identify charged particles (π ± /p/p etc.), and present the inclusive charged pion production cross sections in bins of true momentum using 58 and 120 GeV/c p+C interactions for both the data and
