نویسندگان
چکیده
We study the interactions of the octet baryons in a relativistic meson exchange approach connecting free-space and in-medium interactions with those in finite (hyper)nuclei. A short sketch of the model including the relativistic T-and G-matrix and the mapping of the G-matrix onto density dependent vertex functionals in the density dependent rel-ativistic hadron field theory (DDRH) is given. From new spectroscopic data on medium mass hypernuclei we extract the single particle spectrum including spin-orbit splitting. An extraction of the Λω vector-and tensor vertex as well as the Λσ-vertex shows a strong breaking of SU(3) symmetry.

In the vicinity of the quark-hadron critical point, in the phase diagram of QCD, simple power-law relations constrain the mid-rapidity net-baryon density profile, for different heavy-ion processes, in a unifying scheme. The corresponding scaling variable specifies the proximity of a given experiment to the critical point. An important phenomenological aspect of the critical properties in the ba...

Using the Dirac-Hartree-Fock-Bogoliubov approximation to study nuclear pairing, we have found the short-range correlations of the Dirac 1 S 0 pairing fields to be essentially identical to those of the two-nucleon virtual state at all values of the baryon density. We make use of this fact to develop a relativistic separable potential that correctly describes the pairing fields.

We employ the Nambu Jona–Lasinio model to determine the vacuum pressure on the quarks in a baryon and hence their density inside. Then we estimate the baryonic masses by implementing the local density approximation for the mean field quark energies obtained in a uniform and isotropic system. We obtain a fair agreement with the experimental masses.

We study baryons and baryonic matter in holographic QCD with D4/D8/D8 multi-D brane system. In large-Nc holographic QCD, the baryon appears as a topologically nontrivial chiral soliton, which is called “brane-induced Skyrmion”. We also analyze the features of the baryonic matter in holographic QCD by investigating the system of single braneinduced Skyrmion on a three-dimensional closed manifold...

The s-wave interactions of the baryon decuplet with the octet of pseudoscalar mesons is studied in a unitarized coupled channel approach. We obtain a fair agreement for mass and width of several 3 2 − resonances. In particular, the Ξ(1820), the Λ(1520) and the Σ(1670) states are well reproduced. Other resonances are predicted and also the couplings of the observed resonances to the various chan...
