Abstract :
In the past few years, a program has been setup at KVI in order to study the effects of three-nucleon forces in various reactions. Several observables in elastic and break-up channels in proton-deuteron scattering have been measured and compared with the state-of-the-art Faddeev calculations using modern two-body potentials and a number of three-body forces. Results show that, despite the successes of the calculations in predicting many observables, there are serious discrepancies calling for further investigation of the three-body forces.
