Tjon line in few-body systems

Physical Review C, 1979
We present numerical results of the deuteron-triton binding energy correlation. Moreover, we also give theoretical explanations for this phenomenon in the four-body case.NUCLEAR STRUCTURE $^{2}\mathrm{H}$, $^{3}\mathrm{H}$, $^{4}\mathrm{He}$ binding energy correlations, calculations and model predictions.

Scales and Universality in Few-Body Systems

Few-Body Systems, 2011
The role of scales in the physics of large few-body systems is reviewed. They are evidenced by considering weakly-bound three and four particles, where point-like interactions are regularized and renormalized in a procedure characterized by the emergence of physical scales fixed by observables.

Few Body Systems Made of Pseudoscalars

Few-Body Systems, 2012
Few body systems made of pseudoscalars, like \({K\, K \, \bar K,\,\pi \, K \, \bar K}\) , are studied within a coupled channel approach based on solving the Faddeev equations considering two-body chiral t-matrices as input. As a result, we have found dynamical generation of several states which can be associated with some of the pseudoscalar states ...

Photoreactions in few body systems: Polarization experiments

Progress in Particle and Nuclear Physics, 1995
Abstract Some of the most recent results obtained at the LEGS-BNL facility in the field of photonuclear reactions using polarized photons are reviewed. Sensitivity to E2 excitation of the Δ stimulated the study of π 0 photoproduction and Compton scattering on the proton.

Quasifree processes and FEW-body systems

Czechoslovak Journal of Physics, 1974
The progress achieved during the last two years in the understanding of quasifree processes in three- and four-nucleon systems and evidence for quasifree reaction mechanisms in more complex systems are presented. Some applications of quasifree processes are discussed.

Continuum structure of few-body systems

2023
The focus of this work is on the study of states on the unphysical sheets of the complex energy plane for few-particle systems using potentials derived from leading order pionless effective field theory. The aim is to obtain a statement about the continuum structure of the three-neutron system. For this purpose, various methods are applied. These allow

MESON REACTIONS WITH FEW BODY SYSTEMS

1976
Publisher Summary This chapter discusses the meson reactions with few-body systems. The amplitude for pion-nucleus scattering can be calculated in one of two ways. The first way includes calculating the multiple scattering series in which the pion is scattered off the individual nucleons.

Atomic few-body systems with muonium

Journal of Physics B: Atomic, Molecular and Optical Physics, 2017
Properties of some few-body systems which include one positively charged muon and two electrons are discussed. In particular, we consider the negatively charged muonium ion Mu (or ) and four-body MuPs (or ) systems, each of which has only one stable bound (ground) state. The problem of annihilation of the electron–positron pair(s) in the MuPs system is

Quarks in NN and Few-Body Systems

1987
Starting from the modern QCD vacuum picture an outline is given of the confinement, spontaneous breaking of chiral symmetry (SBCS) and effective Lagrangians of quarks and pions. Hadron models are shortly discussed with an emphasis on comparison of bag models and quark potential model (QPM). NN interaction is derived in the framework of QPM and compared
