Abstract: Constraints on the spin-averaged Λp scattering length and effective range have been obtained from measurements of the pp → pK+Λ reaction close to the production threshold by comparing model phase-space Dalitz plot occupations with experimental ones. The data fix well the position of the virtual bound state in the Λp system. Combining this with information from elastic Λp scattering measurements at slightly higher energies, together with the fact that the hyperdeuteron is not bound, leads to a new determination of the low energy Λp scattering parameters.
