Approach for the three-body force effect in the optical limit approximation: application to hadron-deuteron elastic scattering at high energies

An approach for the three-body force effect in the optical limit approximation is suggested. The differential cross sections of p −, and π− − d elastic scattering at 1.75 and 12.8 GeV c for incident proton, 2 GeV c for anti-proton and 9 GeV c for pion are studied. The D-state and phase variation eff...

Description
Summary:An approach for the three-body force effect in the optical limit approximation is suggested. The differential cross sections of p −, and π− − d elastic scattering at 1.75 and 12.8 GeV c for incident proton, 2 GeV c for anti-proton and 9 GeV c for pion are studied. The D-state and phase variation effects are considered. The experimental data is well described including the 2π-exchange three-body force. The three-body force effect, in this approach, plays a principal role over the complete range of momentum transfer square where the data is available.
