| contents | This work provides the first combined analysis of low-energy p$Λ$ scattering, considering both cross section and correlation data. The obtained results establish the most stringent constraints to date on the two-body p$Λ$ 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 $f_0, f_1 = (2.1, 1.56)$ to $(3.34, 1.18)~$fm. With a chiral NY potential fine-tuned to those scattering parameters, the in-medium properties of the $Λ$ are explored and a potential depth of $U_Λ= -36.3\pm 1.3 \mathrm{(stat)}^{+2.5}_{-6.2}\mathrm{(syst)}$ MeV is found at nuclear matter saturation density. |
