                      asymmetry in $D^0 → K^+ K^-$ and $D^0 → π^+π^-$ decays
                      is performed at the LHCb experiment using proton-proton
                      collision data recorded at a center-of-mass energy of
                      13 TeV, and corresponding to an integrated luminosity of
                      5.4 fb$^{-1}$. The $D^0$ mesons are required to originate
                      from semileptonic decays of b hadrons, such that the charge
                      of the muon identifies the flavor of the neutral D meson at
                      production. The asymmetries in the effective decay widths of
                      $D^0$ and $\bar{D}^0$ mesons are determined to be
                      $A_Γ(K^+K^-)=(-4.3±3.6±0.5) × 10^{-4}$ and
                      $A_Γ(π^+π^-)=(2.2±7.0±0.8) × 10^{-4}$, where the
                      uncertainties are statistical and systematic, respectively.
                      The results are consistent with CP symmetry and, when
                      combined with previous LHCb results, yield
                      $A_Γ(K^+K^-)=(-4.4±2.3±0.6) × 10^{-4}$ and
                      $A_Γ(π^+π^-)=(2.5±4.3±0.7) × 10^{-4}$.},
