Hypernuclei and baryon-baryon interaction

Russian Physics Journal, 1997
A central ΛN potential containing spin and charge dependences is constructed on the basis of an analysis of fundamental hypernuclear data (Λp scattering, the binding energies of the ground and excited states of hypernuclei). The lightest hypernuclei ( Λ 3 H, Λ 4 H, Λ 4 He) are calculated as a system of three or four particles on the basis of the highly

Meson-Baryon and Baryon-Baryon Reactions in a Quark Model

Physical Review, 1966
An "independent-quark model" for mesons and baryons which recently was applied very successfully to elastic scattering at high energies, is extended to inelastic meson-baryon and baryon-baryon reactions. A number of relations between cross sections are derived, most of which are independent of $\mathrm{SU}(3)$.

Meson-baryon coupling constants and baryon-baryon interactions

Nuclear Physics A, 1998
Abstract We present a chiral-invariant SU( 3 ) Lagrangian describing the interactions of the baryon octet with the lowest-mass meson nonets. Empirical estimates for the strengths of these vertices are given. The nonlinear realization of the chiral symmetry generates pair-meson interaction vertices, the coupling constants for which contain no new free

Strongly baryon-dominated disk galaxies at the peak of galaxy formation ten billion years ago

Nature, 2017
In the cold dark matter cosmology, the baryonic components of galaxies—stars and gas—are thought to be mixed with and embedded in non-baryonic and non-relativistic dark matter, which dominates the total mass of the galaxy and its dark-matter halo. In the

Baryon-Baryon Interactions and the Eightfold Way*

Physical Review, 1963
The deuteron is shown to belong to a ten-dimensional irreducible representation of the group $\mathrm{SU}(3)$ in the symmetry scheme called the eightfold way. The baryon-baryon states, which together with the deuteron comprise this supermultiplet, are studied.

Recent soft-core baryon–baryon interactions

Nuclear Physics A, 2005
Recent results obtained with the extended-soft-core (ESC) interactions are presented. In a unified manner the ESC-model, describes nucleon-nucleon (NN), hyperon-nucleon (YN), and hyperon-hyperon (YY), using (broken) SU F (3)-symmetry. In the ESC approach to baryon-baryon (BB) the dynamics is derived from (i) one-boson-exchanges (OBE), (ii) two-meson ...
