Results are presented from the measurement by ATLAS of long-range (∣Δη∣>2|Delta eta |>2∣Δη∣>2) dihadron angular correlations in s=8sqrt{s}=8s ​=8 and 13 TeV pp collisions containing a Z boson. The analysis is performed using 19.4 fb−1mathrm {fb}^{-1}fb−1 of s=8sqrt{s}=8s ​=8 TeV data recorded during Run 1 of the LHC and 36.1 fb−1mathrm {fb}^{-1}fb−1 of s=13sqrt{s}=13s ​=13 TeV data recorded during Run 2. Two-particle correlation functions are measured as a function of relative azimuthal angle over the relative pseudorapidity range 2<∣Δη∣<52<|Delta eta |<52<∣Δη∣<5 for different intervals of charged-particle multiplicity and transverse momentum. The measurements are corrected for the presence of background charged particles generated by collisions that occur during one passage of two colliding proton bunches in the LHC.
