“…Various observables in elastic and break-up reactions, such as differential cross sections, analyzing powers, spin correlations, and spin-transfer coefficients, have been measured at these energies exploiting (polarized) beams of protons and deuterons, partly in combination with polarized targets.

Signatures of three-nucleon interactions in few-nucleon systems

et al. 2011

View full text Add to dashboard Cite

Recent experimental results in three-body systems have unambiguously shown that calculations based only on nucleon-nucleon forces fail to accurately describe many experimental observables and one needs to include effects which are beyond the realm of the two-body potentials. This conclusion owes its significance to the fact that experiments and calculations can both be performed with high accuracy. In this review, both theoretical and experimental achievements of the past decade will be underlined. Selected results will be presented. The discussion on the effects of the three-nucleon forces is, however, limited to the hadronic sector. It will be shown that despite the major successes in describing these seemingly simple systems, there are still clear discrepancies between data and the state-of-the-art calculations.

“…A systematic investigation of 3NFs through the breakup reaction has been initiated at KVI in a common effort between the Dutch and the Polish groups since the end of the 90s by developing various experimental setups and exploiting high-quality polarized beams [21,[24][25][26][27][28]. BINA 1 is the latest experimental setup which was exploited at KVI for few-nucleon scattering experiments.…”

Analyzing powers in $$d(\vec {p}, pp)n$$ at intermediate and large scattering angles at 190 MeV

Understanding of the exact nature of three-nucleon forces is the most challenging topic in the field of nuclear physics. Three-nucleon break-up reaction is a good tool to look into the underlying dynamics of the nuclear force, thanks to its rich kinematical phase space which has different levels of sensitivity to three-nucleon force effects. The recent studies on few-nucleon systems have revealed that the current nuclear force models cannot describe nucleon-deuteron scattering data accurately. In the present work, the analyzing powers of the proton-deuteron break-up reaction obtained using a 190 MeV polarized proton beam will be discussed. We present for the first time the vector analyzing powers for the kinematics in which one of the protons scatters to intermediate and large scattering angles at this energy. The results are particularly useful to study the high-momentum components of the nuclear force. The results show a fairly good agreement with various theoretical predictions for both intermediate and large scattering angles of the break-up phase space.PACS. 21.45.+v Few-body systems -13.75.Cs Nucleon-nucleon interactions arXiv:1910.13605v1 [nucl-ex]

“…These two-nucleon forces (2NF), however, generally underestimate the experimental binding energies of light nuclei [1,2] and this fact indicates the necessity of taking into account three-nucleon forces (3NF). In addition, an indication of 3NF is observed in high-precision deuteron-proton elastic scattering data at intermediate energies [3][4][5]. Various signatures of 3NF in experimental/theoretical studies are reviewed in [6] (the role of 3NF in the context of low-momentum nuclear forces, see Bogner et al [6]).…”

Short-distance repulsion in three-nucleon forces from perturbative quantum chromodynamics

2012

View full text Add to dashboard Cite

We investigate the short-distance behavior of three-nucleon forces (3NF) defined through the Nambu-Bethe-Salpeter (NBS) wave functions using the operator product expansion and calculating anomalous dimensions of ninequark operators in perturbative quantum chromodynamics (QCD). As in the case of NN forces considered previously, we show that 3NF have repulsions at short distance at one-loop, which becomes exact in the short-distance limit thanks to the asymptotic freedom of QCD. Moreover, these behaviors are universal in the sense that they do not depend on the energy of the NBS wave function for three nucleons.
