Most signatures of new physics have been studied on the transverse plane wrt the beam direction at the LHC. We propose the analysis of inclusive longitudinal (pseudo)rapidity correlations among final-state particles in multiparticle production as a complementary signature in the quest for (Un)particles belonging to a Hidden Sector beyond the SM. To this aim, we examine inclusive and semi-inclusive particle correlations functions, forward-backward correlations, and factorial moments of the (charged) multiplicity distribution without resorting to any particular model, but under very general (though simplifying) assumptions. Motivated by analysis techniques (Levy stable law and Ginzburg-Landau analyses) already 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)fractal structure of parton cascades in pp collisions. Results from our preliminary study seem encouraging for possible dedicated studies at the LHC and Tevatron experiments.
