    "abstract": "We consider constraints on the isoscalar S-wave pi-N scattering length a+\nfrom pi-deuteron scattering, to third order in small momenta and pion masses in\nchiral perturbation theory. To this order, the pi-deuteron scattering length is\ndetermined by a+ together with three-body corrections that involve no\nundetermined parameters. We extract a novel value for a combination of\ndimension two low-energy constants which is in agreement with previous\ndeterminations.",
