Signatures of (Un)particles from a Hidden Sector in multiparticle dynamics at Tevatron/LHC

The study of multiparticle dynamics in hadron-hadron collisions at Tevatron and LHC could provide useful information on new physics in addition to the expected signatures on the transverse plane. We suggest that an analysis of inclusive correlations between emitted particles in pp inelastic collisions, and factorial moments of multiplicity distributions, may be helpful in uncovering (un)particles from Hidden Sectors, using underlying events tagged by hard products like high-pT leptons and photons, and applying stringent selection criteria like event shape variables, etc.
