Abstract
We attempt here to understand successfully some crucial aspects of J/Ψ-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.
