This paper reports the first measurement of the cosmic muon flux at the Stawell Underground Physics Laboratory using eight plastic scintillator panels, yielding a value of (6.33 ± 0.04_stat ± 0.35_sys) × 10⁻⁸ s⁻¹ cm⁻² that aligns well with simulations and features significantly reduced uncertainty compared to modeling.
This paper proposes that a minimal dark scalar with a mass of approximately 9.40 GeV, which shares high- fragmentation scaling with NRQCD color-octet production, can simultaneously explain the anomalous high- plateau in nuclear modification factors, the vanishing elliptic flow, and the quarkonium polarization puzzle in heavy-ion collisions while evading historical low- constraints.
