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

Future of Baryons

Nuclear Physics A, 2005
A personal view upon the future of baryon studies is presented, with an emphasis on the quark–pion dynamics, in relation with new hadron spectroscopy triggered by arrival of pentaquarks, as well as at the baryon structure as revealed in proton scattering/production processes in hadron and heavy ion collisions.

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 ...

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

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 $\mathrm{SU}(3)$.

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.

High-Spin Baryons. I. The Pion-Baryon-Baryon Vertex

Physical Review, 1966
A simple analysis is given for the coupling of a pion to baryons of arbitrary spins and parities. The structure of the vertex depends on a new quantum number called $\ensuremath{\gamma}$ parity. Recursion formulas are given relating high-spin vertices to lower spin vertices.
