      abstract     = {Elastic nucleon-pion scattering amplitudes are computed
                      using lattice QCD on a single ensemble of gauge field
                      configurations with $N_f = 2+1$ dynamical quark flavors and
                      $m_π$ = 200 MeV. The s-wave scattering lengths with both
                      total isospins I=1/2 and I=3/2 are inferred from the
                      finite-volume spectrum below the inelastic threshold
                      together with the I=3/2p-wave containing the $Δ$(1232)
                      resonance. The amplitudes are well-described by the
                      effective range expansion with parameters constrained by
                      fits to the finite-volume energy levels, enabling a
                      determination of the I=3/2 scattering length with
                      statistical errors below 5\%, while the I=1/2 scattering
                      length is somewhat less precisely evaluated. Systematic
                      errors due to excited states and the influence of higher
                      partial waves are controlled, providing a step toward future
                      computations down to physical light quark masses with
                      multiple lattice spacings and volumes.},
