Description
Correlations in the angular distribution of particle pairs over large separations can act as sensitive probes of phenomena beyond the Standard Model, such as those predicted in Hidden Valley (HV) frameworks. In this work, a scenario involving a hidden sector with QCD-like dynamics is investigated, where the interplay between HV radiation and standard partonic cascades could intensify and broaden azimuthal patterns among final-state particles. Our detector-level simulation assesses the feasibility of observing these effects at future $e^+ e^-$ colliders, whose cleaner collision environments offer a distinct advantage over hadron colliders like the LHC. A key observable is the possible emergence of unexpected features in the two-particle correlation function, potentially signalling new physics at play.
