“…In our previous work, a systematic investigation of the (pseudo) rapidity distribution was carried basing upon the two-cylinder model. [20] Combined with the present work, we may say that the two-cylinder model describes uniformly the (pseudo) rapidity and transverse momentum distributions.…”

Invariant neutral pion (𝜋 0 ) yields in Au-Au and Cu-Cu collisions and invariant 𝜋 0 cross sections in p-p collisions are studied in the framework of a two-cylinder model. The considered distributions of neutral pions at the maximum energy of the relativistic heavy ion collider (RHIC) have a tail part in the region of high transverse momentum. A two-component distribution based upon the two-cylinder model is used to describe the experimental data of the PHENIX collaboration.

“…Recently, following the Feynman gas picture [12,21], a semi-empirical formula based on the formation and decay of two "cylinders" has been formulated to account for the (pseudo)rapidity distributions of charged particles in hadronic inelastic collisions [22]. At high enough energy, both projectile and target cylinders are expected to overlap only partially, developing a rapidity gap between both fragmentation regions.…”

Most signatures of new physics have been studied on the transverse plane with respect to the beam direction at the LHC where background is much reduced. In this paper we propose the analysis of inclusive longitudinal (pseudo)rapidity correlations among final-state (charged) particles in order to search for (un)particles belonging to a Hidden Sector beyond the Standard Model, using a selected sample of p-p minimum bias events (applying appropriate off-line cuts on events based on, e.g., minijets, high-multiplicity, event shape variables, high-p ⊥ leptons and photons, etc) collected at the early running of the LHC. To this aim, we examine inclusive and semi-inclusive two-particle correlation functions, forward-backward correlations, and factorial moments of the multiplicity distribution, without resorting to any particular model but under very general (though simplifying) assumptions. Finally, motivated by some analysis techniques employed in the search for Quark-Gluon-Plasma in heavy-ion collisions, we investigate the impact of such intermediate (un)particle stuff on the (multi)fractality of parton cascades in p-p collisions, by means of a Lévy stable law description and a Ginzburg-Landau model of phase transitions. Results from our preliminary study seem encouraging for possible dedicated analyses at LHC and Tevatron experiments.

“…We have faith in the common property in the different collisions and hope to describe the particle productions in different collision processes by an uniform consideration. In our recent work [11,12], the (pseudo)rapidity distributions of charged particles produced in p(d)A and AA collisions over an energy range from 400 A MeV to 100 A TeV and in e + e − and pp annihilations at available high energies are uniformly described by a formula.…”
