Production of J/Ψ\Psi-Particles at RHIC and LHC energies: An Alternative `Psi'-chology

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.Comment: 14 pages, 7 figures, to appear in Open Journal of Microphysics. arXiv admin note: substantial text overlap with arXiv:0906.2612, arXiv:1110.5582, and overlap with arXiv:1103.6269, arXiv:1007.451

On Production of Hadrons in Proton-Proton Collisions at RHIC and LHC Energies and an Approach

From the very early days of Particle Physics, both experimental and theoretical studies on proton-proton collisions had occupied the center-stage of attention for very simple and obvious reasons. And this intense interest seems now to be at peak value with the onset of the Large Hadron Collider (LHC)-studies at TeV ranges of energies. In this work, we have chosen to analyse the inclusive cross-sections, the rapidity density, the $K/\pi$ and $p/\pi$-ratio behaviours and the $$-values, in the light of the Sequential Chain Model (SCM). And the limited successes of the model encourage us to take up further studies on several other aspects of topmost importance in particle physics with the same approach.Comment: 14 pages, 3 tables, 7 figures; to appear in Journal of Modern Physic

Prinosi čestica, skaliranje antiprotona i prosječni poprečni impulsi u sudarima olovo–olovo na visokoj energiji: modelska studija

The study aims at explaining the behaviour of some of the very important observables measured in the latest lead-lead collisions at CERN in the light of a variety of the sequential chain model. Calculated values, to our surprise, are in excellent agreement with the measurements, especially when the effect of cascading and rescattering is empirically introduced in the calculations of the average transverse momenta. Implications of the results are discussed.Pokušavamo objasniti svojstva nekih vrlo važnih opservabli koje su u CERNu mjerili u najnovijim sudarima olovo–olovo i to na osnovi inačice modela lančastih nizova. Na naše iznenađenje, izračunate su vrijednosti u izvrsnom skladu s ishodima mjerenja, posebice kada se kaskade i višestruko raspršenje iskustveno uvedu u račun poprečnih impulsa. Raspravljaju se posljedice usporedbi
