In continuation of our series of works on the phenomenological studies on production of particles in various high-energy collisions, we attempt here to deal exclusively with some very crucial aspects of Au-Au collisions at RHIC-BNL. With emphasis on understanding the qualitative and quantitative properties of several important observables related to Au-Au interactions at RHIC, we have also endeavored to analyze and assess, if possible, the limits to the successes and failures of such absolutely phenomenological approaches. As all the models in the domain of high-energy physics are invariably and essentially phenomenological in nature, we have also tried to pinpoint the main and major constrictions of and constraints on these approaches-cum-models. By this yardstick, even the so-called Standard Model (SM), which is too greatly lauded and taken for granted ,cannot escape our critical remarks that are cast on the general framework of what is termed 'phenomenology', in the realm of physics in particular and of science in general.

Insistant sur la comprehension des proprietes qualitatives et quantitatives de plusieurs observables relies aux interactions Au-Au au RHIC, nous nous sommes employes a analyser et a evaluer, si possible, les limites des succes et des echecs de telles approches totalement phenomenologiques. Comme tous les modeles en physique des hautes energies sont essentiellement phenomenologiques en nature, nous avons aussi essaye de circonscrire les contraintes et restrictions les plus importantes et centrales de ces approches et modeles. Selon ce point de vue, meme le celebre Modele Standard qui est loue au dela de toute proportion et pris comme acquis ne peut echapper a ce type de critique dans un cadre general des theories phenomenologiques en physique en particulier et en sciences en general.

Our focus in this work would be concentrated on trying to understand the nature of some very important observables measured for deuteron-gold (d + Au) collisions at relativistic heavy ion collider (RHIC) energies in the light of a particular phenomenological model that we had applied earlier in analyzing data for PP collisions at RHIC and Fermi National Accelerator Laboratory (FNAL) energies with a fair degree of success. In this particular case, as well, our observations and conclusions are exactly similar to those in our previous work. The emphatic ending points, on the whole, to some gross limitations of the chosen phenomenological approach in particular and of the phenomenology as such in general. PACS Nos.: 13.60.Hb, 13.60.Le, 13.60.Rj, 13.85.Ni Le present travail vise a ameliorer notre comprehension de la nature de quelques observables importantes mesurees dans les collisions deuteron-or (d + Au) aux energies du RHIC, a la lumiere d'un modele phenomenologique particulier que nous avons precedemment utilise avec succes dans l'analyse des donnees de collisions p-p aux energies du RHIC et de FNAL. Dans le cas present, nos observations et conclusions sont exactement similaires a celles de nos travaux precedents. La conclusion porte sur les limites de l'approche phenomenologique choisie et sur les approches phenomenologiques en general. [Traduit par la Redaction], 1. Introduction Studies on the high-energy particle-particle, particle-nucleus, and nucleus-nucleus reactions have nowadays entered into crucial phase and stage, with the latest well-agreed revelation that a 'new' state (not quark-gluon-plasma [...]

Interpretation and understanding of high-energy PP data in a clear, consistent, and comprehensive manner is crucial for making valid claims to build up any successful theoretical framework for particle interactions. We have tried here to analyze the various sets of PP data available from the pre-ISR days to the latest PP collisions at the relativistic heavy ion collider (RHIC) experiment at [square root of sNN] = 200 GeV in the light of a power-law model. Both mid-rapidity and high-rapidity data sets have been dealt with by applying the same working formula. It is found that the working formula used provides a good description of these wide ranging data sets; but hardly throws any deep insights into the nature of particle interactions that force us to question the worth and rigour of phenomenological studies. PACS Nos.: 13.60.Hb, 13.60.Le, 13.85.Ni L'interpretation et la comphehension des donnees p-p a haute energie dans un cadre clair, coherent et complet, sont cruciales pour pretendre pouvoir construire un modele theorique valide de l'interaction entre les particules. Nous avons essaye ici d'analyser dans un modele en loi de puissance les differents ensembles de donnees p-p disponibles, debutant avec les donnees pre-ISR jusqu'aux experiences RHIC a [square root of sNN] = 200 GeV. Nous avons utilise les ensembles de rapidite moyenne et elevee en leur appliquant la meme formule de travail. Nous trouvons que la formule de travail utilisee donne une bonne description sur une large gamme de donnees, mais cela ne jette aucune lumiere sur la nature de l'interaction entre particules, ce qui nous pousse a questionner la valeur et la rigueur des modeles phenomenologiques.

Introduction and the background Multiparticle production phenomena involving hadron-hadron interactions still constitute a very exciting topic, as the particle production mechanisms are not yet properly understood even for this [...]
