Abstract
New phenomena involving pseudorapidity and azimuthal correlations among final-state particles in pp collisions at the LHC can hint at the existence of hidden sectors beyond the Standard Model. In this paper we rely on a correlated-cluster picture of multiparticle production, which was shown to account for the ridge effect, to assess the effect of a hidden sector on three-particle correlations concluding that there is a potential signature of new physics that can be directly tested by experiments using well-known techniques.

Being sensitive to any observable deviation from a conventional hadronization process, the correlations are especially suited to search for new physics beyond the Standard Model as predicted, e.g., by some Hidden Valley models [6,7]
Summary
New phenomena involving pseudorapidity and azimuthal correlations among final-state particles in pp collisions at the LHC can hint at the existence of hidden sectors beyond the Standard Model. We introduce the following notation: ρ2(s)(φs1,φs2)≡(1/σs) d2σs/ dφs1dφs2 and ρ3(s)(φs1, φs2, φs3) ≡ (1/σs) d3σs/dφs1dφs2dφs3 for double and triple HS production cross sections, respectively; ρ(1), ρ2(1) and ρ3(1) represent one-, two- and three-particle densities from single cluster decay.
