    The 18th International Conference on Strangeness in Quark Matter (SQM ) will focus on new experimental and theoretical developments on the role of strange and heavy-flavour quarks in high energy heavy-ion collisions and in astrophysical phenomena. Scientific topics include: Strangeness and heavy-quark production in nuclear collisions and hadronic interactions . Thereby both scattering and absorption can result from the potential. U(r) = V(r) + iW(r). () The potentials V (r) and W (r) can, in a microscopic approach, be related to the basic nucleon-nucleon interactions. This process of calculating the optical potential is a difficult one.4/5(5).

On one-boson exchange potentials in nucleon-nucleon scattering by Christofer CronstroМ€m Download PDF EPUB FB2

The nuclear force has been the heart of nuclear physics ever since the field was born in with the discovery of the neutron by Chadwick [].

In fact, during the first few decades of nuclear Cited by:   We find, as others, that the real part, the one-boson exchange potential (OBEP), produces many resonances. However, the inclusion of the dominant absorptive part eliminates all of them.

In addition, we find that the N N scattering is sensitive to the unknown, short-range behaviour of this OBEP and, therefore, we question its predictive by: The one-boson-exchange model and the Nijmegen potential The first quantitative meson-theoretic models for the NN interaction were the one-boson-exchange potentials (OBEP).

They emerged after the exper-imental discovery of heavy mesons in the early ’s. In general, about six non-strange bosons with masses below 1 GeV are taken into. One-Boson-Exchange potential and Nucleon-Nucleon scattering This FORTRAN 77 code encompasses the relativistic momentum space One-Boson-Exchange potential (OBEP) and Nucleon-Nucleon scattering.

This chapter focuses on trinucleon properties with one-boson-exchange (OBE) potentials. The properties of the bound three-nucleon systems, 3 H and 3 He, have been the subject of considerable interest.

The theoretical formulations of the problem are now well established, and the numerical methods for solving the equations are such that the wave functions for these Cited by: 6. In the past few years the one-boson-exchange model has been used in a number of different calculations of the nucleon-nucleon scattering amplitudes [ These calculations use various forms of unitarization, and some of them also have dispersion-theoretic refinements such as threshold subtractions [] and N/D integrals [3].Cited by: From a combined analysis of nucleon-nucleon and hyperon-nucleon scattering with a one-boson-exchange-potential-model the NN results are presented.

The model consists of local potentials due to exchanges of members of the pseudoscalar and vector meson nonets and the scalar meson epsilon taken as a unitary singlet. We investigate characteristic properties of On one-boson exchange potentials in nucleon-nucleon scattering book meson-exchange potentials to achieve a simultaneous description of the nucleon-nucleon ({ital NN}) and hyperon-nucleon ({ital YN}) interactions in the (3{ital q})-(3{ital q}) resonating-group.

Computation is essential to our modern understanding of nuclear systems. Although simple analytical models might guide our intuition, the complex­ ity of the nuclear many-body problem and the ever-increasing precision of experimental results require large-scale numerical studies for a.

Among the topics considered are (1) the so-called high-precision nucleon-nucleon potentials that emerged in the mid s, (2) progress in the microscopic description of the intermediate-range On one-boson exchange potentials in nucleon-nucleon scattering book of the nucleon-nucleon interaction in terms of correlated pion-pion and rho-pion exchange and (3) efforts towards a quantitative de.

The two pion exchange potentials are evaluated by carrying out the numerical integrations of three Feynman parameters in the corresponding Feynman diagrams.

The two pion exchange potentials give rise to the attractive force which is quite similar to the effective scalar meson with its mass of ms≃mπ and its strength of at T = 0 by: 2.

These models became known as one-boson-exchange models, which is a reference to the fact that the different mesons are exchanged singly in this model.

The one-boson-exchange model is very successful in explaining essentially all properties of the nucleon-nucleon interaction at low energies [3,4,5,6,7,8,9].

1 Introduction In my talk I want to give a brief overview of recent devel-opements in our understanding of the fundamental nucleon-nucleon (NN) interaction.

Naturally, such a review will be in basically all one-boson exchange models of the NNin. one-boson-exchange (OBE) model [6{11] emerged, which still today is the most economical and quantitative phenomenology for describing the NNinteraction [12{14].

The weak point of this model, however, is the scalar-isoscalar \sigma" or \epsilon" boson, for which empirical evidence remains controversial. Since this. Two-Nucleon Scattering without partial waves using a While realistic momentum-space nucleon-nucleon potentials are available, they are either given in terms of partial-wave expansions, ried out for a chiral next-to-next-leading order NN force and a standard one-boson-exchange potential in [.

A basic foundation for the latter rests on File Size: KB. On the other hand, the nucleon-nucleon interaction with one boson exchange potential (OBEP) is quite successful for reproducing the nucleon-nucleon scattering data.

In fact, there are already sufficiently large numbers of works available for the determination of the shape of nucleon-nucleon potential with one boson exchange processes. The general framework of the different approaches presented in the book is the meson theory of nuclear forces — where no free parameter is introduced — and the many-body treatment of nucleon-nucleon correlations.

The ultimate hope of this world-wide effort is the understanding of the structure of nuclear matter, both in the ground state and. ABSTRACT. Recent developements in our understanding of the fundamental nucleon-nucleon interaction are reviewed.

One of the most fascinating properties of short range interaction is its repulsive nature which is responsible for the stability of strongly interacting matter.

It can bridge the gap between standard textbook material and research literature for those who intend to work in any of the disciplines where nuclear science and technology is going to play an important role in the future.

Nuclear matter is a convenient theoretical laboratory to test many-body theories. When neutron and proton densities are different, the isospin dependence of the nuclear force gives rise to the symmetry energy term in the equation of state.

This quantity is a crucial mechanism in the formation of the neutron skin in nuclei, as well as in other systems and phenomena involved in Cited by: 2.

Nuclear forces (also known as nuclear interactions or strong forces) are the forces that act between two or more bind protons and neutrons (“nucleons”) into atomic nuclei. The nuclear force is about 10 millions times stronger than the chemical binding that holds atoms together in molecules.

Amongst the potentials used at various stages we mention the Paris potential [1], with its intermediate range still widely used are the one-boson-exchange forces, such as the various Bonn [2] and Nijmegen [3] potentials.

In its. The time evolution of vector-meson spectral-functions is studied within a kinetic theory approach. We implement this formalism in a BUU type transport model. Applications focus on ρ and ω mesons being important pieces for the interpretation of the di-electron invariant mass spectrum measured by the HADES collaboration for the reaction C + C at 2 AGeV bombarding energy.

When applied to the nucleon-pion trilinear interaction, we find a nucleon mass renormalization, a nucleon-pion scattering term, and a nucleon-nucleon scattering term present in the second-order dressed Hamiltonian.

Using the NN7C vertex function derived from the Cloudy Bag Model, the nucleon-nucleon coordinate space potential can be calculated.
