Extraction of ND scattering lengths from the Λb → π−pD0 decay and properties of the Σc(2800)+

The isovector and isoscalar ND s-wave scattering lengths are extracted by fitting to the LHCb data of the pD0 invariant-mass distribution in the decay Λb→π−pD0, making use of the cusp effect at the nD+ threshold. The analysis is based on a coupled-channel nonrelativistic effective field theory. We f...
