Abstract
We use a correlation matrix of two-nucleon (2N) potential parameters to investigate correlations among three-nucleon (3N) observables for the elastic nucleon-deuteron (Nd) scattering process. We employ the up-to-date 2N semilocal momentum-space regularized chiral interactions and the phenomenological OPE-Gaussian potential and using the Faddeev formalism we calculate 3N observables and their correlations. As an example, we present the correlation between the differential cross section and the deuteron analyzing power T20.

Report
In this paper, the authors studied possible correlations among various three-nucleon (3N) observables, such as the differential cross section and analyzing powers in nucleon-deuteron scattering. For this, they used some sophisticated models of the two-nucleon (2N) potential, whose parameters are fitted to a recent compilation of 2N experimental data, and also their variations with modified values of the parameters.
Since the constructing of nuclear interaction models (including 3N interactions) is still ongoing subject and not only 2N observables but also 3N observables are important inputs for this. In this sense, the study reported in this paper may provide valuables information to the quest for the nuclear interaction.
