Correlations among two-nucleon scattering observables

We use a covariance matrix of nucleon-nucleon (NN) potential parameters to investigate correlations among neutron-proton (rap) scattering observables. To this end, we employ the up-to-date NN semilocal momentum-space regularized chiral interactions, solve the Lippman-Schwinger equation, and compute NN observables and their correlations. As a result, we present a systematic analysis of the correlation coefficients between the asymmetry P and the depolarisations A, A' observables at two incoming laboratory energies E-lab = 30 MeV and E-lab = 65 MeV.
