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 ...

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 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

Strangeness changing baryon baryon interaction

Nuclear Physics A, 1998
Abstract The weak nonmesonic decay of Λ hypernuclei gives information on the strangeness changing weak baryon baryon interaction. The parity violation of the process has been studied by observing weak nonmesonic decay of polarized Λ hypernuclei. Study of the inverse process pn → p Λ gives much cleaner information on the process. Recent progress on

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.

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-symmetric baryogenesis

Physical Review Letters, 1990
We propose a new scenario of baryogenesis in which baryon number is an exact symmetry of the fundamental Lagrangian. If the global U(1) symmetry associated with baryon number is spontaneously broken at early times (when the temperature was of order 1--100 GeV) then the out-of-equilibrium decay of baryonic scalar particles can yield a cosmic baryon ...

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.
