4 Widths of K̄ - nuclear deeply bound states in a dynamical model
The relativistic mean field (RMF) model is applied to a system of nucle-ons and a ¯ K meson, interacting via scalar and vector boson fields. The model incorporates the standard RMF phenomenology for bound nucleons and, for the ¯ K meson, it relates to low-energy ¯ KN and K − atom phenomenology. Deeply bound ¯ K nuclear states are generated dynamically across the periodic table and are exhibited...
متن کامل¯k-nuclear Deeply Bound States? ∗
Following the prediction by Akaishi and Yamazaki of relatively narrow K̄-nuclear states, deeply bound by over 100 MeV where the main decay channel K̄N → πΣ is closed, several experimental signals in stopped K reactions on light nuclei have been interpreted recently as due to such states. In this talk I review (i) the evidence from K-atom data for a deep K̄-nucleus potential, as attractive as V K̄ (...
متن کاملDynamical distance as a semi-metric on nuclear conguration space
In this paper, we introduce the concept of dynamical distance on a nuclear conguration space. We partition the nuclear conguration space into disjoint classes. This classification coincides with the classical partitioning of molecular systems via the concept of conjugacy of dynamical systems. It gives a quantitative criterion to distinguish dierent molecular structures.
متن کاملOverview of K̄-Nuclear Quasi-Bound States
The K̄-nucleus interaction near threshold is strongly attractive and absorptive as suggested by fits to the strong-interaction shifts and widths of K−-atom levels [1]. Global fits yield ‘deep’ optical potentials with Re VK̄(ρ0) ∼ −(150 − 200) MeV [2–5], whereas more theoretically inclined studies that fit the low-energy K−p reaction data, including the I = 0 quasi-bound state Λ(1405) as input for...
متن کاملA Dynamical Model for Nuclear Structure Functions
We construct a dynamical model for the parton distributions in a nucleus by perturbative evolution of input distributions from a low starting scale. These input distributions are obtained by modifications of the corresponding free nucleon ones; the modifications being determined by standard nuclear physics considerations. The model gives good agreement with existing data. Its extension to the s...
