Constraints on $\Sigma$ Nucleus Dynamics from Dirac Phenomenology of $\Sigma^-$ Atoms

Nuclear Theory 2009-10-28 v1

Abstract

Strong interaction level shifts and widths in Σ\Sigma^- atoms are analyzed by using a Σ\Sigma nucleus optical potential constructed within the relativistic mean field approach. The analysis leads to potentials with a repulsive real part in the nuclear interior. The data are sufficient to establish the size of the isovector meson--hyperon coupling. Implications to Σ\Sigma hypernuclei are discussed.
