Correlated Time-Delay Modes in ATLAS 4-Lepton Data and Proposed Search Band for the QUEST Experiment

Analysis of open ATLAS 13 TeV 4-lepton collision data reveals three statisti-
cally relevant delay modes in the frequency domain of summed lepton energies. The
corresponding time-delay scales (τ ) fall precisely within the sensitivity band of the
QUEST (Quantum Enhanced Space-Time) experiment at Cardiff University, de-
signed to probe high-frequency spacetime fluctuations. This short note summarizes
the extracted modes and recommends the optimal search frequencies for QUEST’s
upcoming multi-month run.
