Abstract
This work provides the first combined analysis of low-energy p scattering, considering both cross section and correlation data. The obtained results establish the most stringent constraints to date on the two-body p interaction, pointing to a weaker attraction than so far accepted. The best set of scattering lengths for the spin singlet and triplet are found to range from to fm. With a chiral NY potential fine-tuned to those scattering parameters, the in-medium properties of the are explored and a potential depth of MeV is found at nuclear matter saturation density.

The initial upload contained a wrong entry in Table 1. The 'f1' for point iv) was WRONGLY written as 1.54 fm, whereas the CORRECT value is 1.32 fm
