Meson-meson correlations in baryon-baryon and antibaryon-baryon interactions [PDF]

Progress in Particle and Nuclear Physics, 1996
Recent work of the Jülich group about the role of meson-meson correlations in baryon-baryon and antibaryon-baryon interactions is reviewed.

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 $\mathrm{SU}(3)$.

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

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.

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

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 ...

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.

Baryon-baryon interactions and unitary symmetry

Il Nuovo Cimento, 1964
The baryon-baryon interactions are studied by making use of the octet version of the unitary symmetry model. The bound state Ξ−n in the1S0 state is predicted provided that the symmetry is not violated seriously. The Ξ-n → Σ−Σ0 process occurs only through the space-spin svmmetric state.

Perturbative QCD, Baryons, and Baryon Resonances

1989
We will discuss applications of QCD using perturbation theory to baryons1,2 and to the baryon resonances. The subjects that nuclear physicists study are changing and Quantum Chromodynamics (QCD) is presumably the correct theory for the strong interactions, so that this is a suitable subject for this institute.
