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

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 ...
