“…As argued in [118] multi-source structure in hadron collisions has a clear influence on the correlations among emitted particles. As the number of independent sources increases, correlations are diluted, as experimentally observed in p-A versus p-p and e + e − collisions [34,100,106]. Indeed, from Eq.…”

“…A very instructive description of the behaviour of R 2 (y 1 , y 2 ) is provided by a two-dimensional plot in which contour-lines for R 2 values are shown for p-p collisions [98]; similar analyses have been performed for proton-emulsion interactions [100]). If one cuts the dimensional plot by planes along lines of fixed y 1 it is generally found a peculiar triangular shape pointing out the existence of shortrange correlations (SRC) [98,100,101], of order of one unit of rapidity. We will turn to these issues in sections 5.3 and 5.4.…”

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.
