Measurements of the azimuthal correlations of muon pairs from heavy-flavor decays in 5.02 TeV Pb+Pb collisions with the ATLAS detector

This analysis measures azimuthal correlations and yields of muon pairs that arise from decays of heavy-flavor (HF) quarks in Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}}$=5.02 TeV. The distributions of muon pairs in azimuthal angle separation $\Delta\phi$, are measured, and corrected to account for c...

description This analysis measures azimuthal correlations and yields of muon pairs that arise from decays of heavy-flavor (HF) quarks in Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}}$=5.02 TeV. The distributions of muon pairs in azimuthal angle separation $\Delta\phi$, are measured, and corrected to account for combinatorial muon pairs. The correlated yields on the away-side ($\Delta\phi=\pi$) and widths of the away-side peak are measured as a function of collision centrality separately for same- and opposite-charge pairs. A significant suppression of the HF-muon pairs from peripheral to central collisions is observed. However, the widths of the angular correlation do not show a significant modification with centrality.
