We present recent investigations on the tensor and anomalous tensor form factors of the nucleon based on the SU(3) chiral quark-soliton model. We also show the transverse spin densities of the nucleon, emphasizing the strange quark spin densities inside a nucleon.

In the bare nucleon-nucleon force, the tensor force coming from the pion exchange explains the large amount of the nuclear binding energies. In the nuclear wave function, the 2p2h excitation involving high momentum component is essential to describe the strong tensor correlation. In this study, we investigate the role of the tensor force in the light nuclei.
We employ a shell model type...

Tensor correlations play an important role in a nuclear system. A realistic interaction, which reproduces the nucleon-nucleon scattering, implies short-range repulsion and strong tensor components. In this contribution, we investigate the structure of the tensor correlations in light nuclei. We obtain highly correlated many-body states with an explicitly correlated basis which enables us to...

One of the most important subjects of nuclear physics is
to understand the origin of the elements surrounding us.
In this talk I will focus on 12C, an essential element for
life. It is well known that 12C is formed from three alpha
(4He) particles in stars. Theoretical description of this
reaction, however, has been oversimplified. I will explain
how to formulate reaction rate of a...

In this talk, we present the recent developments in the strange production via hadron photoproductions, taking into account the theoretical and experimental progresses, achieved by us and the experimental collaborations at SPring-8 and Jefferson laboratory. We focus on the Lambda(1520) photoproduction with the Feynman-Regge interpolation prescription, which interpolates the low- and...

We present an extended Brueckner-Hartree-Fock (EBHF) theory for understanding the nuclear structure as a consequence of bare interaction among the constituent particles in medium and heavy nuclear system. The nuclear force is characterized by the strong tensor force induced by pion exchange interaction. To handle the strong tensor force based on the single-particle picture, the Hartree-Fock...

We study the properties of nuclear matter in the extended Brueckner Hartree-Fock theory with a realistic nucleon-nucleon (NN) interaction. The nuclear wave function is composed of traditional Hartree-Fock states and 2-particle-2-hole (2p-2h) states. The two important characters of the realistic NN interaction, strong tensor force and short range repulsion of the central force can be properly...

We construct the relativistic equation of state (EOS) of dense matter
covering a wide range of temperature, proton fraction, and density
for the use of core-collapse supernova simulations.
The study is based on the relativistic mean-field (RMF) theory,
which can provide an excellent description of nuclear matter and
finite nuclei. The Thomas-Fermi approximation is adopted to describe...

A level splitting between a spin doublet, spin-orbit splitting, can be a good measure of spin- orbit coupling in nuclei. Ando-Bando and Pieper-Pandharipande investigated microscopic origins of the 1p spin-orbit splitting in ^{16}O and showed that about half of the splitting originates from the NN spin-orbit interaction and the remaining part from the NN tensor and three- nucleon interactions....

The spin-isospin excitation modes in nuclei have been instrumental for
the understanding of nuclear structure for the several decades.
Spin-dipole (SD) $(L=1,S=1,J^{\pi}=0^{-},1^{-},2^{-})$ excitations have
been under extensive theoretical studies.
Isovector $0^{-}$ excitations are of particular interest
since they carry the simplest pion-like quantum number.
The distribution of...

The tensor interaction which originates from the pion exchange is
an essential interaction that provides the important two-body
attraction in the nuclear forces. The importance of the tensor
force has been demonstrated to reproduce the properties of
nuclear matter as well as to explain the binding energies of
the deuteron and alpha particles. In heavier nuclei, results from...

The low-lying excited states of $^{10}$Be and $^{12}$Be are investigated within a no-core Monte Carlo Shell Model (MCSM) framework employing a realistic potential obtained via the Unitary Correlation Operator Method. The excitation energies of the 2$^+_1$ and 2$^+_2$ states and the B(E2;$\,2^+_{1}\rightarrow$ 0$^+_{g.s.}$) for $^{10}$Be in the MCSM with a treatment of spurious center-of-mass...

There is a strong tensor interaction in the nucleon-nucleon interaction due to the pion exchange interaction. The tensor interaction cannot be treated within the Hartree-Fock approximation. We have developed an extended Brueckner-Hartree-Fock theory to treat the tensor interaction. With the use of the Bonn potential we are able to reproduce the saturation property of nuclear matter. We can...
