Chiral 3NF and neutron-deuteron scattering
نویسندگان
چکیده
Results on three-nucleon (3N) elastic scattering below the pion production threshold are discussed with emphasis on the need for a three-nucleon force (3NF). The large discrepancies found between a theory based on numerical solutions of 3N Faddeev equations with (semi)phenomenological NN potentials only and data point to the need for 3NF’s. This is further supported since another possible reason for the discrepancies in elastic nucleon-deuteron ( Nd) scattering, relativistic effects, turned out to be small. Results for chiral NN (at N2LO and N3LO) and 3NF’s (at N2LO) are shown and discussed.

Complete set of total cross sections for imaginary parts of nd forward scattering amplitudes, and three-nucleon force effects
In neutron-deuteron scattering, four total cross sections are shown to form a complete set for the determination of the imaginary parts of the forward amplitudes by means of the optical theorem. The amplitudes are decomposed into scalar and tensor components in spin space. Contributions of three-nucleon forces ~3NF! to these amplitudes are studied by Faddeev calculations. Significant effects of...

In the neutron-deuteron scattering, four total cross sections are shown to form a complete set for the determination of the imaginary parts of the forward amplitudes because of the optical theorem. The amplitudes are decomposed into scalar and tensor ones in the spin space. Contributions of threenucleon forces (3NF) to these amplitudes are studied, by the Faddeev calculation, which predicts sig...
متن کاملThe Missing Three-Nucleon Forces: Where Are They?
In recent years, there has been substantial progress in the derivation of nuclear forces from chiral effective field theory. Accurate two-nucleon forces (2NF) have been constructed up to next-to-next-to-next-to-leading order (NLO) of chiral perturbation theory and applied in microscopic nuclear structure calculations with a good degree of success. However, chiral three-nucleon forces (3NF) have...

Available data on large-angle nucleon-deuteron elastic scattering N d → dN below the pion threshold give a signal for three-body forces. There is a problem of separation of possible subtle aspects of these forces from off-shell effects in two-nucleon potentials. By considering the main mechanisms of the process N d → dN , we show qualitatively that in the quasi-binary reaction N + d → (N N) + N...
متن کاملDeuteron Compton Scattering: A Random Walk
In this sketch, some recent developments in Compton scattering off the deuteron are reviewed. The strong energy-dependence of the scalar magnetic dipole polarisability βM1 turns out to be crucial to understand the data from Saskatoon at 94 MeV. Chiral Effective Field Theory is used to extract the static iso-scalar dipole polarisabilities as ᾱs = 12.6± 1.4stat ± 1.0wavefu and β̄ s = 2.3± 1.7stat ...
