چکیده
We investigate the in-medium properties of hyperons and anti-hyperons in framework Non-Linear Derivative (NLD) model. focus on momentum dependence strangeness optical potentials. The NLD model is based simplicity well-established Relativistic Mean-Field (RMF) approximation, but it incorporates an explicit a field-theoretical level. extension to (anti)baryon-octet formulated spirit SU(6) G-parity arguments. It shown that with appropriate choice cut-offs $\Lambda$, $\Sigma$ $\Xi$ potentials are consistent recent studies chiral effective field theory Lattice-QCD calculations over wide region. In addition, we present predictions for $\overline{\Lambda}$-, $\overline{\Sigma}$- $\overline{\Xi}$-hyperons. This work important future experimental such as CBM, PANDA at Facility Antiproton Ion Research (FAIR). relevant nuclear astrophysics too.

Momentum-dependent nuclear mean fields and collective flow in heavy-ion collisions.
We use the Boltzmann-Uehling-Uhlenbeck model to simulate the dynamical evolution of heavy ion collisions and to compare the effects of two parametrizations of the momentum–dependent nuclear mean field that have identical properties in cold nuclear matter. We compare with recent data on nuclear flow, as characterized by transverse momentum distributions and flow (F ) variables for symmetric and ...
متن کاملRelativistic Mean-Field Model with Momentum-Dependent Self-Energies
The conventional relativistic mean-field model with minimal meson-nucleon couplings is extended by introducing derivative meson-nucleon couplings. Combining this approach with a density dependence of the coupling vertices leads to an improved description of nuclear matter and atomic nuclei, especially of effective masses and the optical potential. Introduction and Theoretical Model The relativi...
متن کاملChemical Equilibration of Antihyperons
Rapid chemical equilibration of antihyperons by means of the interplay between strong annihilation on baryons and the corresponding backreactions of multi-mesonic (fusion-type) processes in the later, hadronic stage of an ultrarelativistic heavy ion collision will be discussed. Explicit rate calculations for a dynamical setup are presented. At maximum SPS energies yields of each antihyperon spe...
متن کاملFour-momentum boosted Fermion fields
A formulation of the fermion action is discussed which includes an explicit four momentum boost on the field prior to discretisation. This is used to shift the zero of lattice momentum to lie near one of the on-shell quark poles. The positive pole is selected if we wish to describe a valence quark, and negative pole for a valence antiquark. Like NRQCD, the typical lattice momenta involved in ha...
