Three-pion correlation functions versus $Q_3$ for $0.16< K_{\rm{T,3}} < 0.3$ GeV/$c$ in pp, p-Pb and Pb-Pb collision data compared to PYTHIA, DPMJET and HIJING generator-level calculations. Top panels are for same-charge triplets, while bottom panels are for mixed-charge triplets. Two points at low $Q_3$ with large statistical uncertainties are not shown for the pp same-charge correlation function.
