Lattice QCD study of $\pi \Sigma -\bar{K}N$ scattering and the $\Lambda (1405)$ resonance

John Bulava, Bárbara Cid-Mora, Andrew D. Hanlon +8

A lattice QCD computation of the coupled channel $\pi \Sigma -\bar{K}N$ scattering amplitudes in the $\Lambda (1405)$ region is detailed. Results are obtained using a single ensemble of gauge fiel…
