A STUDY OF NUCLEON FORCES WITH REPULSIVE CORES: II. LOW ENERGY PROPERTIES, PARTICULARLY CHARGE INDEPENDENCE

The low energy properties of two-nucleon potentials with infinite repulsive cores have been studied by numerical calculations using an electronic digital computer. The consequences of assuming charge independence for the nuclear force in the 1S state have been examined by performing computations with several potential shapes for both the neutron–proton and proton–proton systems. It was found that this assumption severely restricts the possible potential shape. Charge independence occurs with the Yukawa potential for zero core radius. Potentials that are more singular at small distances than the Yukawa require larger core radii; less singular potentials are not charge independent.

Abstract In this work, we extended our statistical model with charmed and bottomed hadrons, and fit the quark creational probabilities for the heavy quarks, using low energy inclusive charmonium and bottomonium data. With the finalized fit for all the relevant types of quarks (up, down, strange, charm, bottom) at the energy range from a few GeV up to a few tens of GeV’s, the model is now considered complete. Some examples are also given for proton–proton, pion–proton, and proton–antiproton collisions with charmonium, bottomonium, and open charm hadrons in the final state.

Charge Dependence

Deuteron breakup reactions are basic laboratories for testing nuclear force models. Recent improvements in the data analysis allow for direct identification of neutrons in the BINA detection setup. This opens up the opportunity to study new aspects of few-nucleon system dynamics like charge dependence of nuclear force or Coulomb interaction. In this paper we determine regions along the kinematical curves where differential cross section of deuteron-proton breakup reactions can be measured by the proton-neutron and proton-proton coincidences simultaneously. %In this paper we determine regions along the kinematical curves where differential cross section of $^1$H$(d,pp)n$ and $^1$H$(d,pn)p$ breakup reactions overlap. This is particularly useful for validation of the neutron detection technique.

Potential Form

The interaction of two nucleons in the form of protons and neutrons as a bound system in the local potential, known as the deuteron, has been investigated. Two-nucleon interaction potential field through the core will produce a nuclear force where the force between nucleons is generated by the exchange of mesons. One of the members of the group of meson particles is pion. Pion can be chargedπ + ,π -or neutral,π 0. Interaction potential form of the simplest is the exchange of one pion potential (OPEP), V OPEP , which has a radially independent of Yukawa potential. In this study, the first step taken is to perform discretization of the OPEP potential expression coupled with the equation of the boundary conditions due to the influence of interaction distances. The next step is to implement a programming technique to obtain the value associated with the potential influence of OPEP in the deuteron, the magnitudes of the static deuteron, such as a pion distance exchange, and mass estimates pion involved in this interaction.
