      abstract     = {In this work, we analyze the semi-leptonic decays
                      B¯0/D0→(a0(980)±→π±η)l∓ν within light-cone sum
                      rules. The two and three-body light-cone distribution
                      amplitudes (LCDAs) of the B meson and the only available
                      two-body LCDA of the D meson are used. To include the
                      finite-width effect of the a0(980), we use a scalar form
                      factor to describe the final-state interaction between the
                      πη mesons, which was previously calculated within
                      unitarized Chiral Perturbation Theory. The result for the
                      decay branching fraction of the D0 decay is in good
                      agreement with that measured by the BESIII Collaboration,
                      while the branching fraction of the B¯0 decay can be tested
                      in future experiments.},
