      abstract     = {A lattice QCD computation of the coupled channel
                      πΣ–K¯N scattering amplitudes in the Λ(1405) region is
                      detailed. Results are obtained using a single ensemble of
                      gauge field configurations with Nf=2+1 dynamical quark
                      flavors and mπ≈200  MeV and mK≈487  MeV.
                      Hermitian correlation matrices using both single baryon and
                      meson-baryon interpolating operators for a variety of
                      different total momenta and irreducible representations are
                      used. Several parametrizations of the two-channel scattering
                      K-matrix are utilized to obtain the scattering amplitudes
                      from the finite-volume spectrum. The amplitudes, continued
                      to the complex energy plane, exhibit a virtual bound state
                      below the πΣ threshold and a resonance pole just below the
                      K¯N threshold.},
