Abstract
We attempt here to understand successfully some crucial aspects of $J/\Psi$-production in some high energy nuclear collisions in the light of a non-standard framework outlined in the text. It is found that the results arrived at with this main working approach here is fairly in good agreement with both the measured data and the results obtained on the basis of some other models of the `standard' variety. Impact and implications of this comparative study have also been precisely highlighted in the end.
Highlights
The study of the J/Ψ-mesons in ultra-relativistic heavy ion collisions has consistently been considered to be a potentially powerful tool for studying the properties of the hypothetical ‘hot and dense matter’ created in these collisions
The observed nuclear effects in J/Ψ production in AA collisions is interpreted as a combination of final state interaction (FSI) of J/Ψ in the dense medium, and the initial state interaction (ISI) effects in production of J/Ψ caused by multiple interactions of the colliding nuclei
Let us proceed to apply the chosen model to interpret some recent experimental results of J/Ψ-production reported by various groups for different collisions like p + p, d + Au, Cu + Cu, Au + Au at Relativistic Heavy Ion Collider (RHIC) and p + p, Pb + Pb at Large Hadron Collider (LHC)
Summary
The study of the J/Ψ-mesons in ultra-relativistic heavy ion collisions has consistently been considered to be a potentially powerful tool for studying the properties of the hypothetical ‘hot and dense matter’ created in these collisions. Rather our primary intent would centre around understanding and interpreting the nature of data of inclusive cross-sections and some other important observables of J/Ψ mesons in BNL-RHIC and CERN-LHC experiments. We define our objectives here as: 1) to explain the main and major features of the latest data on J/Ψ-production in BNL-RHIC and CERN-LHC experiments from the proposed alternative approach built up by us in a set of previous works done in the both the remote and recent past [6,7] and 2) to compare our model-based calculations with some other competing models. In the last section (Section 5) we offer the final remarks and the conclusions arrived at
