The problem of the structure nucleons and their interaction in concept nonperturbative QCD is discussed as an approach to studying transformation current quarks into constituent ones search for mechanism such a transformation, creating bulk nucleon mass. Attention drawn possibilities offered by central nucleon-nucleon collisions this aspect.

Between the initial excitation of nucleons by the passing throughout each other and the final cascading of newly created hadrons there should be considered one more step. We call it the second step cascading process. It acts as an interaction of wounded nucleon from one nucleus with another nucleon from the same nucleus. This mechanism leads to the significant increase on the inelasticity for n...

We report on variational calculations of the energy E(p, ß) of asymmetric nuclear matter having p = p +pp = 0.05 to 0 .35 fm-~, and ß = (P -p~)lp = 0 to l . The nuclear hamiltonian used in this work consists of a realistic two-nucleon interaction, called °i<, that fits the available nucleon-nucleon scattering data up to 425 MeV, and a phenomenological three nucleon interaction adjusted to repro...

The weak interaction between nucleons remains one of the most poorly-understood sectors of the Standard Model. A quantitative description of this interaction is needed to understand weak interaction phenomena in atomic, nuclear, and hadronic systems. This paper summarizes briefly what is known about the weak nucleon-nucleon interaction, tries to place this phenomenon in the context of other stu...

Approximate analytical formulas for the self-consistent renormalization of P,T-odd and P-odd weak nuclear potentials by the residual nucleon-nucleon strong interaction are derived. The contact spin-flip nucleon-nucleon interaction reduces the constant of the P,T-odd potential 1.5 times for the proton and 1.8 times for the neutron. Renormalization of the P-odd potential is caused by the velocity...

We calculate at two-loop order in chiral perturbation theory the electromagnetic corrections to the dominant two-pion exchange nucleon-nucleon interaction that is generated by the isoscalar πN contact-vertex proportional to the large low-energy constant c 3. We find that the respective 2πγ-exchange potential contains sizeable isospin-breaking components which amount to about −1% of the strongly...

In this paper, we first give a brief review of the theoretical framework for microscopic shell-model calculations starting from the free nucleon-nucleon potential. In this context, we discuss the use of the low-momentum nucleon-nucleon interaction V low−k in the derivation of the shell-model effective interaction and emphasize its practical value as an alternative to the Brueckner G-matrix meth...

We study the short-range nucleon-nucleon interaction in a chiral constituent quark model by diagonalizing a Hamiltonian comprising a linear confinement and a Goldstone boson exchange interaction between quarks. The six-quark harmonic oscillator basis contains up to two excitation quanta. We show that the highly dominant configuration is | sp[42]O [51]FS > due to its specific flavour-spin symmet...

We use the induced interaction of Babu and Brown to derive two novel relations between the quasiparticle interaction in nuclear matter and the unique low momentum nucleon-nucleon interaction Vlow k in vacuum. These relations provide two independent constraints on the Fermi liquid parameters of nuclear matter. We derive the full renormalization group equations in the particle-hole channels from ...

We present realistic models of pion-exchange three-nucleon interactions obtained by fitting the energies of all the 17 bound or narrow states of 3 ≤ A ≤ 8 nucleons, calculated with less than 2% error using the Green’s function Monte Carlo method. The models contain two-pion-exchange terms due to πN scattering in Sand P-waves, three-pion-exchange terms due to ring diagrams with one ∆ in the inte...
