Abstract |
Correlations in the angular distribution of particle pairs over large separations can act as sensitive probes of phenomena beyond the Standard Model (SM), 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 enhance and broaden azimuthal patterns among final-state particles. Our detector-level simulation assesses the feasibility of observing these effects at future lepton colliders, whose cleaner collision environments offer a distinct advantage over hadron colliders like the LHC. In particular, building upon previous studies on linear colliders, results are presented for the FCC-ee using an ILD-like detector concept adapted to the FCC environment. |
