The Effect of Various Three-Body Forces on Nuclear Matter and Neutron Stars Properties
Abstract—The binding energy per nucleon for nuclear matter, i.e., equation of state (EOS), within the Brueckner–Hartree–Fock (BHF) approach with the consideration of various three-body forces (3BFs) like the phenomenological 3BF and by adding a contact term to the BHF calculations are considered at variance densities. The 3BF contribution turns out to be nonnegligible contribution and to have a substantial saturation ... إقراء المزيد

Tensor Target Spin Asymmetries in Coherent π0-Photoproduction on the Deuteron Including Intermediate ηNN Interaction Within a Three-Body Approach
Motivated by the recent measurements from the VEPP-3 electron storage ring, we investigate the tensor target polarization asymmetries T2M (M = 0, 1, 2) in the reaction γ d → π0d with a particular interest in the effect of the intermediate ηNN three-body approach. This approach is based on realistic separable representations of the driving two-body interaction in the πN, ... إقراء المزيد

Spectral Functions of Nuclear Matter using Self-Consistent Green's Function Approach based on Three-Body Force
A self-consistent Green's Function approach is used to study the in°uence of short range correlations beyond the mean field approach of nuclear matter. The ladder equation, including both particle-particle and hole-hole propagation, is solved in nuclear matter for a realistic interaction derived from the CD-Bonn potential. The hole- hole interaction is used to calculate the spectral functions that describe the ... إقراء المزيد

Asymmetric nuclear matter and neutron star properties within the extended Brueckner theory
Microscopically, the equation of state (EOS) and other properties of asymmetric nuclear matter at zero temperature have been investigated extensively by adopting the non-relativistic Brueckner-Hartree-Fock (BHF) and the extended BHF approaches by using the self-consistent Green’s function approach or by including a phenomenological three-body force. Once three-body forces are introduced, the phenomenological saturation point is reproduced and the theory is ... إقراء المزيد

The Thermal Properties of Asymmetric Nuclear Matter within the Extended Brueckner–Hartree–Fock Approach
The single-particle potentials and other properties at absolute zero temperature in isospin asymmetric nuclear matter are investigated in the frame of an extended Brueckner theory. Also thermal quantities are calculated in asymmetric nuclear matter using CD-Bonn potential and the Urbana three-body forces (3BF). Also, the effects of the hole–hole contributions are investigated within the self-consistent Greens function approach. The inclusion ... إقراء المزيد

Tensor target spin asymmetries in incoherent (π−)-photoproduction off the deuteron including rescattering effects
Tensor target spin asymmetries T2M (M=0,1,2) in the reaction γd → π−pp are studied for photon energies from π-threshold up to 1.5 GeV with inclusion of rescattering effects. It is shown that the influence of rescattering effects on the tensor target spin asymmetries is sizable in the energy region near π-threshold. At higher energies, much smaller influence of rescattering effects ... إقراء المزيد

EOS of Neutron Matter and Neutron Star Properties
The Equation of State (EOS) of pure neutron matter at zero temperature is calculated up to five saturation densities within the Brueckner theory with the inclusion of three-body forces. Three different realistic and accurate two-body forces are considered to evaluate the G-matrix effective interaction for nuclear matter. These models are the chiral N3LO, the CD-Bonn and the Argonne V18, which ... إقراء المزيد

Microscopic and bulk properties of symmetric nuclear and pure neutron matter with chiral N3 LO nucleon-nucleon force
We have studied the single-particle properties and the equation of state (EOS) of symmetric nuclear and neutron matter within the framework of the Brueckner-Hartree-Fock (BHF) approach extended by including a phenomenological three-body force (3BF). Adding the 3BF to the initial two-body force (2BF) and applying a partial-wave expansion, G-matrix calculations are performed in pure neutron matter as well as in ... إقراء المزيد

The properties of nuclear matter at zero and finite temperatures
The properties of nuclear matter are studied in the frame of the Brueckner theory. The Brueckner-Hartree-Fock approximation plus two-body density-dependent Skyrme potential which is equivalent to three-body interaction are used. Various modern nucleon-nucleon potentials are used in the framework of the Brueckner-Hartree-Fock approximation, e.g.: CD-Bonn potential, Nijm1 potential, and Reid 93 potential. These modern nucleon-nucleon potentials fit the deuteron properties ... إقراء المزيد

The Equation of State of Nuclear Matter and Neutron Stars Properties
The equation of state (EOS) of symmetric nuclear and pure neutron matter has been investigated extensively by adopting the non-relativistic Brueckner-Hartree-Fock (BHF). For more comparison, the extended BHF approaches using the self-consistent Green’s function approach or by including a three-body force will be done. The EOS will be studied for different approaches at zero temperature. We can calculate the total ... إقراء المزيد
