Proton-deuteron break-up studies with BINA and a review of
three­-nucleon database

Finding a suitable theory of nuclear forces is one for the main goals in subatomic physics. In the present thesis, the vector analyzing power, Ay, Ax and the cross section are extracted for the first time. Moreover, we performed for the first time a global review of a rich set of cross section and vector analyzing-power data taken with a proton-beam energy of 135 MeV and 190 MeV using a Dalitz analysis. The results were compared with theoretical calculations from Faddeev calculations using 2N and 2N+3NF models for the kinematics in which both protons scatter to polar angles smaller than 30 and with a relative azimuthal opening angle varying between 20 and 180 in steps of 20.

For most of the configurations, the results at small and large relativeazimuthal angles show a different behavior when comparing data with theory. Besides the five-fold differential study of the break-up reaction, wealso performed a more global comparison of our data with theoreticalcalculations using four types of quantities. For the first quantity, weaverage the vector analyzing powers and cross sections over S for eachconfiguration. For the second quantity, we performed a chi-square analysis for several azimuthal and polar angles.To show the results for all configurations and combinationof angles, the third quantity was developed. For the last quantity, we explored a Dalitz analysis in terms of twoLorentz invariant quantities for the cross sections and analyzing powers.
