Search for three-body force contribution in the break-up of deuterons by protons

The existence and manifestation of three body forces in few nucleon break-up experiments have been the topics of increasing interests since long ago. In this direction, the best testing table has been the nucleon-deuteron system, alpha-deuteron system being treated as the next candidate due to highly stable character of alpha particle. With the advent of time, there have been a large collection of high precision experimental data along with highly rich different theoretical approaches like those based on Faddeev theoretical calculations. The present article aims at searching the possible contribution of 3BF effects in the realization of the existing discrepancies in the experimental distribution of three-body correlation cross sections in the proton induced break-up of deuterons at two incident energies and three chosen correlated pairs of angles. The present investigation, supplemented with the existing Faddeev type calculations (without 3BF), points toward incorporation of 3BF contributions, rather significantly, for better understanding of the experimental data, at both the higher and lower incident energies and the co-linearity conditions considered. However, analyzing the data in the light of the recent state-of-the-art Faddeev type calculations, including Coulomb interaction as well as 3BF effects, is likely to be most important for precise understanding of the problem
